What makes it special

Premium PPSU Material

PPSU (Polyphenylsulfone) is a high-performance material used in medical devices that require repeated sterilization. It is extremely durable, heat-resistant, and does not absorb odor or color. Grosmimi PPSU bottles are available in the original PPSU yellow and a newly released dark grey.

Made from liquefied silicone—the same material used for baby bottle nipples—the straw offers a familiar texture that feels gentle and natural for babies. This helps them transition to using a straw without resistance, while the cross-cut design prevents leaks and backflow for a cleaner drinking experience.

Parents ask, science answers.

What makes PPSU safer than regular plastic?

PPSU (Polyphenylsulfone) is a medical-grade polymer used in surgical instruments. Unlike standard PP or PC plastics, PPSU releases 2,750x fewer microplastics when exposed to heat — verified by peer-reviewed research published in Nature Food (2020). It contains zero BPA, BPS, or BPF.

How do I sterilize Grosmimi products?

PPSU withstands temperatures up to 180°C. You can boil, steam-sterilize, or UV-sterilize safely. Our products are rated for 1,000+ sterilization cycles with zero degradation — no warping, no discoloration, no chemical leaching.

What age range are your products designed for?

Grosmimi products cover ages 0 to 4 years, mapped to developmental milestones. Baby bottles for 0–6 months, straw cups for 6–18 months, tumblers for 18–36 months, and tableware for 12–48 months. Each product is engineered for the specific motor and oral development stage.

Is the straw cup really leak-proof?

Yes. Our patented PureSeal system uses a weighted stainless-steel ball and silicone valve to create a zero-leak seal in any orientation. Sideways, upside-down, in a diaper bag — guaranteed leak-proof or your money back.

Why is Grosmimi more expensive than other brands?

Standard PP bottles cost less because polypropylene is cheap — but it releases millions of microplastic particles per feeding. PPSU is a medical-grade material that costs significantly more to manufacture. Combined with SUS316 stainless steel components and precision engineering, the price reflects genuine material science, not marketing.

Where can I buy Grosmimi products?

Grosmimi is available on Amazon, our official Shopify store, and through select retailers including Target, Nordstrom, and Babylist. International shipping is available through our online store.

Do you offer a warranty or guarantee?

Every Grosmimi product comes with a leak-proof guarantee and a 1-year warranty against manufacturing defects. If your product leaks or shows signs of material degradation under normal use, we will replace it — no questions asked.
