I am selling a set of 4 KP DECO socks. The size of each is 21-23cm. Please check photos 4, 7, and 10 for the materials. The sock on the far right is a high sock, and the color is charcoal gray. Photo 9 shows a similar color. Although unopened, these items 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.
