These are school socks. There are four pairs of socks that are about 10 to 12 cm above the ankle, and one pair that is about 15 cm. Also, the size of the left and middle socks are 22 to 24 cm, and the right one is 24 to 26 cm. The middle ones were a set of three, but only one was used, so there are two left. Thank you for looking.
