The Momcozy Breast Milk Storage Bags are designed with a specialized double-zip sealing system to keep your precious breast milk fresh for your baby. The bags come in a perfect pack size to support new parents in the first few months of expressing and storing breastmilk.The color-changing milk bags provide an easy visual indicator of the milks temperature. Purple means the milk is too cold below 36C/96.8F, blue indicates the ideal feeding temperature 36-40C/96.8-104F, and white signals the milk is too hot above 40C/104F. This allows parents to quickly and accurately monitor the milks temperature and ensure it is at the perfect warmth for feeding.

• Bags can be frozen flat or upright, allowing for quick defrosting or freezing.
• Each bag has double-sealed side seams and a double zipper to protect and preserve the breastmilk.
• BPA/BPS-free.
