● Grosmimi bottles are made of PPSU.
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.
