Premium PPSU Material

PPSU (Polyphenylsulfone) is a type of high performance polymer. Material commonly used for medical devices requiring repeated steam sterilization. It is incredibly durable and temperature resistant.

PPSU is perfect material for baby bottles or cups. It is a plastic but has the benefits of glass. Which does not absorb odor or color and you can sterilize without any deformation.

There is no better choice.

Now there are two types of PPSU body colors. One is the original PPSU color yellow and the other is dark grey which is newly released.

What is PPSU?

The safe material, PPSU, is a lightweight yet highly durable and heat-resistant medical-grade material, making it safer to use without the risk of shattering like glass.

When should I replace the straw, and how?

Grosmimi grows with your child! Start with a baby bottle and easily switch to a straw cup by changing the parts—no need to buy a whole new cup.

EASY TEAT: Available in 4 stages:
(Stage 1: 1–3 months, Stage 2: 3–5 months, Stage 3: 5–8 months, Stage 4: 8 months+)

SPOUT: Great for babies (4M+) starting baby food early.

WEIGHTED KIT: Helps babies (6M+) drink from any angle while holding the cup.

STAGE 1 STRAW: A super soft straw (6M+), made from the same material as baby nipples, helps babies transition to straw drinking comfortably.

STAGE 2 STRAW: A firmer straw (12M+) for older babies. The flow is the same as Stage 1, but the silicone is stronger. Switch to Stage 2 when babies start chewing more.

Silicone straws & mouthpieces: Every 2-3 months
PPSU bottle: Every 6-12 months
Replacement timing may vary based on usage.

What’s the difference between stage 1 and stage 2 straws?

First-stage: Softer, for beginners or non-chewers.
Second-stage: Firmer, for children over 12 months who chew frequently.
Grosmimi cups come with first-stage straws by default.

How do I sterilize Grosmimi straw cups at home?

It can also be hygienically maintained through various sterilization methods, including boiling, steam sterilization, dishwasher, UV sterilization, and microwave sterilization.

What is the function of an air valve?

It helps regulate pressure balance when there is a difference between internal and external pressure, requiring a pinch to function properly. This feature is especially useful when there is a temperature difference with external environments, such as warm water, and plays a crucial role in preventing leaks.

How do I choose the right cup size?

If your baby is new to straw cups, the shorter 200ml size is often easier for them to handle. For basic use like water or small quantities of liquids, 200ml is sufficient. If your child drinks more or if you plan to fill it with milk or other beverages, a 300ml cup is recommended.
