These are socks that were worn when my child first entered kindergarten. The size is from 9cm to 14cm. The colors were easy to match, so they weren't too noticeable when worn. They also have anti-slip grips on the soles of the feet, and the size is marked, so you won't forget it. There's also a space in the middle to put a name sticker, so I recommend them. There are no noticeable scratches or stains, but there is some sign of use.
