Breastmilk is liquid gold; so it deserves special storage! The First Years Breastflow Milk Storage Organizer has a spring-loaded drawer that freezes milk flat and pushes it up front for easy access. Simply load the rack from the back for 'first-in, first out' storage. Snap the cover on to keep breast milk isolated from other items in the freezer or you can use this breastmilk storage organizer to hold bags for extra storage. You pumped it, now protect it with this breastmilk organizer!
