This is a set of 9 pairs of socks. I bought a lot of these for kindergarten, and since these are still in good condition, I'm selling them. I rotated through various socks for two months, so there are no tears or damage. The sizes are: Olaf socks are 13-15 cm, white high socks are 15-18 cm, and the rest are about 16-18 cm. How about these for the upcoming season, to wear with skirts at kindergarten, daycare, or school?
