When you’re pumping your breast milk, sometimes storing excess milk is necessary. Often, breast milk storage bags are clunky, breakable and hard to maneuver, but not the Pump & Safe Bags from Medela. You can pump or pour your milk very easily into these bags without leaks, spills or mishaps. The overall design is convenient and straight forward, and you can use these bags with any Medela pump design. Prep ahead, and store bags in freezer or fridge. Bags are available in twenty or fifty count units. Adapters are included.
