Thank you for viewing! For freezing and refrigerating breast milk. Breast milk freezer bags, 20 bags per pack! This is a set of 3. Remaining number of bags: 40ml bags (14 remaining) 80ml bags (18 remaining) 160ml bags (17 remaining) 100ml bags (2 remaining) (Since there is no box, they are stored together in the 160ml box) Please check the images 2, 3, 4, and 5! The unused storage bags have not been taken out, so they are new and clean! *The boxes are folded, torn, and not clean. Thank you!
