These are children's socks I bought last year at Murasaki Sports for snowboarding. I only wore them for two days last year, and they're too small this year, so I'm selling them. They are in very clean condition with no pilling. 【Size】 Approximately 18cm when laid flat, so I think they fit sizes around 19-21cm. For reference, I, who am 23cm, could also wear them. They are very stretchy. The length is 27cm from the heel when laid flat. 【Material】 I'm not sure of the details because there's no tag, but it's a very thick and warm material. Please refer to the second photo for the lining. - Color: Red and gray stripes - Material: Warm fabric - Design: Striped design - Size: Kids' size Thank you for looking.
