<Hegen> If you replace it with a baby bottle cap, it will quickly turn into a food stocker where you can store baby food and snacks. It has a highly airtight seal, so you don't have to worry about it spilling even if you store pre-made baby food or expressed breast milk, and it prevents oxidation and can be stored hygienically. You can enjoy using it in a variety of ways during the days you spend with your child, such as as a cup for making sweets or as a container for small items, so it is a product that can be used conveniently as your child grows.
*Breast milk can be stored in the refrigerator for 2 days and in the freezer for 3 to 6 months.

Attachable baby mug (55-99-0044-844) and baby straw mug (55-99-0045-844) are also available.
