I am selling a set of 4 pairs of socks: KP DECO socks and lovetoxic sneakers socks (free size). The size is 21-23cm. Please check photos 4, 7, 10, and 13 for the materials. The gray one on the far left is a pair of over-the-knee socks. Although they are unopened, they have been stored at home, so I am selling them as used items. Please consider this before purchasing. Shipping will be via Nekopos. Thank you very much.
