Thank you for viewing. These are children's socks. The size is 15-18cm, and they are ankle-length. I bought them for a boy, but I think they can be used for a girl as well. I bought them for my child, but they were too small, so I'm selling them. They are new and unused, but please refrain from purchasing if you are concerned about home storage. There is a fraying as shown in the fifth photo. I am not selling them individually. I will sell them as a set of 3. I will ship via Rakuraku Mercari.
