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.

Try Grosmimi PPSU.

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.
