I searched and found that the M size for socks is around 12-14cm, so I'm listing it as 13cm. This was received as a bonus. It has been stored unused. I saw yellow spots on the white one. I haven't checked in detail since it's unopened. I plan to ship it in an envelope. Baby socks with animal faces embroidered, set of 5, size M. - Colors: White, Yellow, Green, Pink, Blue - Size: M - Design: Animal faces - Package: Set of 5
