I am also selling this item on other platforms, so please forgive me if it sells out. This is a set of two navy ZETT color socks. (1 new, unused pair and 1 used pair) The size is 24-27cm. They are a long type with increased thickness for durability and a new heel-fit structure that prevents slippage. Perfect for sports such as baseball.
