This is a set of Kaneson baby bottle inner bags and powdered milk easy bags. They are compact and easy to carry when going out or traveling, and are convenient because you can use the baby bottle itself without washing it, just by using one bag. I am selling the remaining bags because my child stopped drinking milk before I could use them all. - Product Name: Disposable inner bags for baby bottles - Quantity: 8 - Product Name: Powdered milk easy bags - Quantity: 19 The outer bags have wrinkles and stains. Please understand that they have been opened before purchasing. If you have any reservations or are concerned about the condition, please refrain from purchasing.
