Set of 2 pairs of socks. These are new and unused, but without tags or packaging. I'm not sure of the size, but they are about 9 cm (see photo 2). Although they are new and unused, the yellow socks have some areas where the rubber appears white, possibly due to the fabric's characteristics. Also, there are several places where the thread is looped. Please check photos 3 and 4. The green socks are fine. Please understand the above before purchasing.
