Thank you for viewing. This is a breast milk storage bag with a capacity of 200ml. There are 3 packs of 10 unopened bags + 1 pack of 6 opened bags, for a total of 36 bags. Although the inner bag of one pack has been opened, the main bag is unused, so there is no problem with use. However, please purchase only if you understand that this is a used item. I will also include 4 Medela breast milk storage bags. Due to shipping costs, I will ship without the outer box, but if you need the outer box, please comment and I will add 200 yen. - Brand: angesmile - Capacity: 200 ml - Quantity: 36 bags Type: Breast milk storage bags
