The Fraupow Breast Milk Storage Bags 30 Pack makes everything easier by using a single pouch to express, store, warm and feed - there is no need to sterilize bottles or transfer milk at any stage. Many mums pump and store milk for future use. Building up a stash is incredibly satisfying. These 250ml breast milk 30-pack storage bags allow you to freeze your milk and store it in a space-saving way. When you need to use it simply defrost it and use the easy pour spout to decant it into a bottle. They stand freely to reduce the risk of spillage. They have an easy pour spout so you don't lose a drop, and they have a leakproof double zipper. It even features an ml measure and space for you to write on the date and time the milk was expressed.
