The first breast milk storage solution in silicone. At last, no more plastic! One for the fridge and one for the freezer, when it’s time to use the milk, they work in bottle heaters or dipped in hot water. The stopper is leak proof and designed with a silicone carry strap so the nursing mom in your life can take them anywhere. Best of all, they are free from BPA, PVC and Phthalates and reusable time and time again. Each bag holds 260 ml (9 oz) of milk. Includes five Kraft paper collection date and time indicating tags.
