I actually ordered it for my granddaughter. These are comfortable ankle socks made from polyester and spandex. They can be machine washed. There are 6 pairs, 3 pairs in black with gold lines at the top and 3 pairs in black and gray with gold lines at the top and diamond pattern under the foot, and they are very elastic. They claim arch support, but you can't really tell.
