Hello, I am selling these because my child has outgrown them. These are unisex and fit waists from 75-105cm. These are L size pull-up diapers from Lifree, with 12 diapers per pack, allowing for 7 uses. - Size: L size - Quantity: 12 diapers - Type: Pull-up diapers - Brand: Lifree - Uses: 7 times I have 2 cases available, but the price is for one. One pack of 12 diapers costs over 2500 yen, so a box containing 4 packs for 6800 yen is a great deal. It's much cheaper than at drug store chains, so I'm sorry, but I can't lower the price any further. Of course, the cardboard box is unopened and the product is new and unused. Due to the large size of the item, I cannot accept returns or refunds after purchase, so please only purchase if you understand this. If you need both cases, I will make it 12800 yen if you comment.
