Product Description
Mitour's first rattle teether — a new sensory axis in the line. ST-2018 extends the program into auditory stimulation. Buyers who already stock the Silicone Turtle Teether (TT-2017) gain a complementary SKU targeting a distinct developmental milestone, not a substitute product.
Built-in dual-end bell rattle delivers auditory development input. Two independent rattle heads each produce a crisp bell sound, providing cause-and-effect training from 3m+. The infant shakes the handle; the sound follows. No separate rattle toy required.
Dumbbell long-handle form enables bilateral motor skill practice. At 182 mm, ST-2018 requires two-hand coordination — a developmental target distinct from the single-hand 3D grip of the Turtle Teether. Buyers targeting bilateral motor programs have a concrete product story.
Triple-sensory stimulation across three modalities. Auditory (crisp bell), Visual (high-contrast color pairing + Smiley Face), and Tactile (three texture zones) activate simultaneously in one 55 g all-silicone object.
Contrast color pairing drives color cognition training. Red + Green Leaf, Pink + Cyan Leaf, Cyan + Pink Leaf — each combination maximizes visual contrast between body and calyx, directly supporting early color differentiation in the 3–6 month window when color perception is actively developing.
All-silicone construction with no exposed hardware. The captive silicone rattle ball is fully enclosed within the outer ring body — no metal pellets, no plastic casings, no removable parts. EN 71-3 compliance confirmed by SGS test reports (3 reports on file).
Cross-sells cleanly with Mitour toy straps. For stroller and high chair use, pair with a Star Silicone Toy Strap, Birds Silicone Toy Safety Straps, or Shell Shape Silicone Toy Straps. ST-2018 + one strap SKU is a natural two-item bundle for any infant travel program.
ST-2018's developmental claim rests on four specific, structurally grounded cognitive skill domains. Each maps to a physical feature of the product.
The 12–13 cm central handle is the primary grip zone. At 182 mm total length, ST-2018 exceeds the reach of a single 3m+ hand, naturally prompting two-hand engagement. Handle Horizontal Ribbed Rings provide tactile grip anchors that stabilize hold during active shaking. This bilateral grasp pattern — two hands, midline crossing, load-bearing at each end — is a direct motor precursor to the two-hand coordination that emerges at 6–9 months. The 55 g weight distributes evenly across the dumbbell axis, producing manageable proprioceptive feedback without arm fatigue. Contrast with the Silicone Turtle Teether (TT-2017) (42 g, single-hand 3D grip on a 112 mm footprint): each product targets a distinct grip development milestone.
Each ST-2018 colorway uses high-chromatic-contrast complementary pairings: Red body against Green calyx, Pink body against Cyan calyx, Cyan body against Pink calyx. High contrast between adjacent color regions is the format most effective for color differentiation training in infants whose retinal cone function is still maturing in the 3–6 month window. The Smiley Face on each rattle head adds a high-contrast face-pattern detail, capitalizing on the documented neonatal preference for face-like stimuli. Together, the contrast-color boundary and Smiley Face create two distinct visual anchors for attention-tracking. ST-2018's contrast pairing is a design specification — structurally different from the solid single-color format of most teethers.
Each rattle head presents a compound geometry: a rounded outer ring body, an inner sphere visible through perforated holes, a scalloped calyx with fanned leaves, and a central Smiley Face panel. This multi-primitive form — convex dome, perforated sphere, fanned leaves — introduces distinct shape categories within a single graspable object. Between 3 and 6 months, infants begin to distinguish shapes through combined oral and manual exploration; ST-2018's rattle heads support that discrimination without requiring multiple objects. The inner ball visible through the circular holes also adds an early depth-perception challenge absent from flat-profile teethers.
Three structurally distinct texture zones are accessible across different grip styles:
Calyx Ribbed Leaves (rattle head top): Longitudinal rib channels on the fan-shaped calyx provide firm, linear gum contact targeting broad molar-zone pressure.
Raised Dot Bumps on Strawberry Body Ring: Raised circular dots concentrate gum pressure onto defined points, producing focused massage at anterior gum ridges where incisors erupt first. Highest-intensity texture zone on ST-2018.
Horizontal Ribbed Rings on Long Handle: Lower-intensity gum stimulation when the infant mouths the shaft — natural when hands have migrated to the rattle heads. Also the primary tactile grip anchor for two-hand holding.
No single grip orientation shuts off all three zones; rotation continuously presents new stimulation combinations.
The rattle function is ST-2018's defining differentiator within the Mitour teether range — absent from all current Mitour teether SKUs, including the Silicone Turtle Teether (TT-2017).
ST-2018 has a rattle head at each end of the dumbbell shaft. Both heads are independent: shaking one end activates the near rattle only; rotating the object activates the other. The infant can learn to isolate cause-and-effect — shake left, hear left; shake right, hear right — as a bilateral spatial audio-motor feedback loop. A single-ended rattle cannot provide this distinction.
Inside each Strawberry Body Ring sits a captive silicone ball with 4–5 evenly distributed circular holes through its surface. The ball moves freely within the enclosed outer ring cavity. When the object is shaken, the inner ball contacts the ring interior wall, producing sound. The circular holes reduce acoustic dampening (producing a cleaner bell-like resonance) and make the inner ball visible from the exterior — adding a depth-perception visual element supporting Skill C. The ball is captive and cannot be removed without destroying the outer ring.
The sound produced is a short, clear, high-frequency tone — consistently described in buyer sample evaluations as a "crisp bell sound." It is distinct from the dull rattle of bead-in-plastic toys and from the metallic ring of traditional bell-in-housing rattles. For infant auditory development, from 3m+ infants begin to orient head and gaze toward sound sources. ST-2018's dual-end format means sound can originate from two distinct spatial positions relative to the infant's midline, training early bilateral sound-localization in a way single-ended rattles cannot.
The rattle sound under normal shaking conditions measures below 65 dB — within the recognized infant hearing safety threshold. All-silicone construction inherently attenuates output relative to hard-casing equivalents. EN 71-3 compliance covers the full silicone compound safety profile; Mitour's SGS test reports are available on request.
When ST-2018 rattles, the Smiley Face on the active rattle head is simultaneously in the infant's visual field. This paired auditory-visual stimulus — a face-like image linked to a sound event — engages audio-visual integration earlier than either stimulus alone. The design is structural, not decorative.

Teething relief, 3–12 months. Three texture zones, two rattle sound sources, and a bilateral handle grip provide enough multi-sensory engagement for the infant to cycle through positions without losing interest during active teething.
Auditory stimulation and cause-and-effect play sessions. From 3m+, shake-triggered sound is one of the earliest intentional play behaviors. ST-2018's dual-end structure allows the infant to learn that shaking left produces left-side sound and shaking right produces right — early bilateral spatial audio-motor mapping.
Bilateral motor skill development. The 182 mm handle requires two-hand engagement. OT supply chains, pediatric developmental toy programs, and NICU follow-up kits have a concrete dimensional rationale for stocking ST-2018.
Color recognition training. The three high-contrast color pairings are designed to deliver color discrimination input during the 3–6 month developmental window. Infant sensory brands with a color-cognition curriculum use ST-2018 as a structured training object.
Travel teether — pair with a Toy Strap. For stroller and car-seat use, loop a Star Silicone Toy Strap (SP-1179) around the handle. Birds Silicone Toy Safety Straps and Shell Shape Silicone Toy Straps attach the same way. Follow EN 12586 ≤22 cm chair/stroller attachment protocol for the strap.
Baby shower gift and premium gift box SKU. ST-2018's contrast-color visual identity and rattle function read as a considered sensory gift. Pair with a Star Toy Strap or Lion Silicone Toy Safety Holder for a complete teether-and-strap gift set in a Pantone-matched color box.
Indie boutique and specialty baby B2C. The strawberry contrast-color aesthetic performs well in DTC infant boutiques. The rattle sound is a retail floor demonstrability feature — buyers pick it up, shake it, and hear the result immediately.
Sensory wall and nursery play kit. Hung from an activity frame via a Toy Strap, ST-2018 functions as a visual-auditory nursery toy alongside fabric, wood, and mirror objects in open-shelf arrangements.
Pediatric clinic waiting room. EN 71-3 certification and all-silicone BPA-free construction satisfy pediatric procurement requirements. Dishwasher-top-rack compatible (with post-cycle cavity check) for facility hygiene protocols.
B2B gift bundles. Corporate new-parent welcome packs and hospital gift sets benefit from ST-2018's full certification stack. Pair with Monster Silicone Toy Straps for a bold-visual B2B gift configuration.
Mitour's OEM program and ODM program support the following customization paths for ST-2018:
Custom Pantone contrast pairing. Any Pantone-matched body color and contrasting calyx color beyond the three stock combinations. Brand-aligned pairings and retailer-exclusive seasonal colorways are both supported. Cross-SKU Pantone alignment with the full Mitour accessory range is available.
Custom Smiley Face or brand graphic. The Smiley Face panel on each rattle head is a defined print area. Brand logos, mascot faces, or custom character expressions replace the standard design via UV full-color or silk-screen. Buyers building character-brand infant programs can anchor ST-2018 to their IP from first touch.
Logo methods (6 available). Roller print · Silk-screen · Laser engraving · UV full-color print · Heat transfer · Water transfer. Primary placement areas: rattle head Smiley Face zone, calyx outer face, handle shaft underside. Laser engraving delivers a permanent mark with no ink migration risk.
Multilingual color box printing. Brand logo, bilingual safety instructions, barcode, QR-code, and EN 71-3 compliance statement in any target-market language. Pantone-matched color box printing standard — packaging contrast color mirrors the product's body-leaf pairing.
ST-2018 is a one-piece molded all-silicone object. The rattle mechanism uses a captive silicone inner ball fully enclosed within the outer silicone ring body — no metal pellets, no plastic inserts, no removable hardware of any kind. There are no bonded sub-components and no mechanical joints. The inner ball cannot exit the outer ring during normal use or under the bite pressures produced by a 3m+ infant.
Before each use: Inspect both rattle heads and the full handle for cuts, tears, or surface thinning. Shake both ends and confirm the rattle sound is clear; a muffled sound may indicate water accumulation in the rattle cavity. EN 71-3 child safety toy compliance covers heavy-metal migration from the silicone compound; SGS test reports (3 reports) available on request.
Age: 3m+ under continuous adult supervision. Do not allow unsupervised use, use during sleep, or use in a carrier where an adult cannot directly observe gum and airway contact.
Rattle sound level: Below 65 dB under normal shaking — within recognized infant hearing safety limits.
When paired with a toy strap: Mitour toy straps (Star, Birds, Shell) are for stroller and chair attachment only — not neck wear. Follow EN 12586 ≤22 cm attachment protocol. ST-2018 itself is an EN 71-3 child safety toy product.
Chemical safety: BPA Free / PVC Free / Phthalate Free / Cadmium Free / Lead Free. Certified under FDA, LFGB (§64 LFGB), EN 71-3, RoHS, and REACH. Full documentation at /capabilities/certifications/.
Hand-wash in warm water (65–80°C) with mild neutral soap; use a soft cloth on the rattle head surfaces.
Rattle cavity water: After washing, hold each rattle head facing downward and shake vigorously to drain. Air-dry until sound returns to full crispness before reuse.
Dishwasher (top rack): Compatible, but requires post-cycle rattle cavity check and air-drying if sound is dampened.
Steam sterilizer and UV-C sterilizer: Compatible. Boiling: Up to 5 minutes for periodic deep cleaning; cool fully before use.
Do not use bleach, oxidizing agents, abrasive scrubbers, or solvent-based cleaners.
Discard immediately on any cut, tear, bite deformation, or rattle sound abnormality. Store clean and dry, away from direct sunlight.

Q1: From what age is the Strawberry Rattle Teether suitable?
ST-2018 is rated 3 months and older, under continuous adult supervision. At 3m+, infants have sufficient hand strength to hold the 55 g dumbbell and produce shaking motions that activate the rattle. Do not use during sleep or without direct adult supervision.
Q2: How loud is the rattle sound? Is it safe for infant hearing?
Below 65 dB under normal shaking — within the recognized infant hearing safety range. All-silicone construction (inner silicone ball against silicone outer ring) produces a softer acoustic output than metal-bell or hard-plastic-bead rattles. No amplification cavity, no metal components.
Q3: What is inside the rattle — is there a metal or plastic ball?
No metal, no plastic. The inner ball is a captive silicone sphere with 4–5 circular holes, fully enclosed within the outer silicone ring body. The entire product is 100% food-grade silicone — BPA Free, PVC Free, Phthalate Free. The inner ball cannot be removed without destroying the outer ring.
Q4: How is it different from the Turtle Teether?
The Silicone Turtle Teether (TT-2017) is a compact 3D handheld silent teether (112 × 90 × 36 mm, 42 g) with four texture zones optimized for single-hand grip and multi-texture oral stimulation. ST-2018 is a 182 mm dumbbell rattle teether (55 g) with dual-end bell rattles, three contrast-color pairings, and a 4-in-1 cognitive skill system anchored to auditory stimulation and bilateral motor development. The two SKUs are complementary, not competitive — stocking both covers a broader developmental program than either alone.
Q5: Can water enter the rattle chamber when washing?
Yes — the perforations in the inner ball allow water ingress during washing. After washing, hold each rattle head facing downward, shake to drain, and air-dry until sound returns to full crispness before reuse.
Q6: Is it dishwasher or sterilizer safe?
Dishwasher (top rack): compatible, but requires post-cycle rattle cavity water check. Steam sterilizer: compatible. Boiling up to 5 minutes: compatible. UV-C: compatible. Hand-washing with warm neutral soap and full air-drying is the recommended routine method.
Q7: Does it contain BPA, PVC, or phthalates?
No. ST-2018 is 100% food-grade silicone — BPA Free, PVC Free, Phthalate Free, Cadmium Free, Lead Free. Certified under FDA, LFGB, EN 71-3, RoHS, and REACH. SGS test reports (3 reports) are available with every sample and bulk order.
Q8: Can I attach it to a toy strap?
Yes — strongly recommended for stroller and travel use. Loop a Star Silicone Toy Strap (SP-1179) around the central handle. Birds Silicone Toy Safety Straps and Shell Shape Silicone Toy Straps attach the same way. Follow EN 12586 ≤22 cm stroller/chair attachment protocol for the strap; ST-2018 is an EN 71-3 child safety toy product.
Q9: What is the MOQ and lead time?
MOQ is 300 pcs. Samples ship within 7 days from artwork approval. Bulk production is 25–35 days from sample sign-off. The three stock color combinations can be mixed within a single order.
Q10: Do you support custom colors and logo printing?
Yes. Any Pantone body color and contrasting calyx color beyond the three stock pairings. Logo methods: roller print, silk screen, laser engraving, UV full-color, heat transfer, water transfer. The Smiley Face panel on each rattle head is the primary custom artwork zone.
Q11: How do I choose between gift box, OPP bag, and blister packaging?
OPP bag suits FBA inbound and B2B wholesale at lowest cost. Color box (Pantone contrast-printed to match the product pairing) suits retail shelves and baby shower gift programs. Blister suits peg-hook POP displays in pharmacy and baby specialty retail. For ST-2018 + Toy Strap bundle packs, contact for unified bundle packaging design.
Q12: What does Disney Standard certification mean for buyers?
Disney Standard audits factory safety, labor compliance, product quality, and environmental management. Mitour (Shenzhen Yuanfeng Xingye Technology Co., Ltd.) passed Disney Standard factory audit in 2022. Full audit documentation available on request. The qualification also confirms Walmart (2019) and Target (2019) supply-chain compliance levels.
