I purchased these on Amazon two years ago and have never used them. I'm selling them on Mercari now, hoping you can use them. The size is indicated as 6T, which I believe is equivalent to 120cm to 130cm. They have never been used. There is no doubt that they are unused. This is a set of 5. Below is the product description from Amazon: 【6-Layer Construction & Powerful Urine Absorption】MooMoo Baby training pants use a 6-layer construction, with 2 layers of cotton + 1 layer of absorbent fabric + 2 layers of waterproof TPU + 1 layer of A-grade fabric, to absorb more moisture and prevent leaks. The TPU waterproof layer in the center of the training pants effectively prevents urine leakage and helps keep the pants and floor dry and clean. These thick-layered training pants have very strong urine absorption, slowing down urine leakage and giving parents enough time to change their baby's training pants. Note ①: MooMoo Baby training pants are not completely waterproof, so it is recommended to use them in conjunction with waterproof pants or waterproof pads during sleep. Note ②: If the toddler has thick thighs, it is recommended to order a size larger. 【Safe and Soft Material】MooMoo Baby's latest training pants use carefully selected soft and gentle high-quality cotton material, perfect for underwear. The outer layer is 100% cotton, and the inner layer is cotton + muslin + TPU. Soft as a cloud, gentle on sensitive skin, ensuring the baby's health, and can be worn for a long time by training pants boys and girls. It brings a comfortable and healthy wearing experience to the baby, allowing the baby to move freely and enjoy toilet training. 【Comfortable Material: Soft Muslin Cotton】MooMoo Baby training pants are made of natural and safe cotton.
