Finally - breast milk storage bags designed by actual moms who understand the challenges of pumping and storing milk! If you've ever had your "liquid gold" (aka: breast milk) ruined by a broken or leaky milk storage bag, you're already well acquainted with the shortcomings of other storage bags. They're cheaply made, flimsy to handle, and the seal you get is tenuous at best. Milkies "No-Break, No-Leak" Storage Bags are different. They're premium milk storage bags made with special reinforced sides to prevent breakage in the freezer. Also, Milkies Storage Bags feature a double-zipper closure system which ensures your milk won't leak out. What's more, Milkies Storage Bags stand upright on their own, allowing you to easily pour your milk into them without spilling a single drop! And of course, as with all Milkies products, Milkies Storage Bags are completely BPA-Free and made from the highest quality, food-grade plastic. For your convenience, helpful milk storage guidelines are printed on every bag. One box of Milkies Breast Milk Storage Bags contains 50 bags.
