The bottle body is made of PPSU material, which is more resistant to falling, abrasion, and high temperature than traditional materials. The straw is made of food-grade silica gel, so it won’t leave any marks when biting, and it’s soft and doesn’t hurt. While ensuring the quality, we also pay attention to the appearance design of the product. We do everything in order to give you better. Using baby-level materials and craftsmanship, it is very suitable for children, pregnant women, and people of all ages.
