These are training pants purchased online in 2025. They are unopened, but have been stored at home, so I would be happy to sell them to someone who understands this. The following is from the sales site: 1. 【Gentle Material for Babies】 The surface is 100% cotton, and the part that touches the skin is made of a comfortable material. It is light, highly absorbent, and breathable, making it more comfortable than diapers. The durable material is also resistant to washing and can be used repeatedly. 2. 【Leak-Resistant 4-Layer Structure】 It has a 4-layer structure consisting of 6 layers of gauze, 1 layer of terry cloth, and 1 layer of TPU waterproof layer, and 100% cotton outer fabric. It can absorb moisture well while also being waterproof. It can be used as overnight pants or as training pants during the day. It is less likely to leak to the outside during naps or when there is a small amount of bedwetting, so you don't have to worry about wetting the sheets or futon. 3. 【Elastic Leg Openings】 It adopts a three-dimensional design that wraps the baby's bottom, fitting snugly to prevent leaks. 4. 【Easy to Put On and Take Off】 The waist is made of elastic material, so it stretches and fits snugly. It is also easy for children to put on and take off themselves. 【Material】 Outer fabric: 100% cotton Middle layer: TPU waterproof Middle lining: Terry cloth Lining: 6 layers of gauze
