This is a set of three pairs of Adidas mesh kids' socks. I've forgotten the size, but I wore them when I was in the 3rd or 4th grade of elementary school. (Probably around 18-21 cm) I checked them before listing, but since they are mesh, there may be some overlooked snags or loose threads. Thank you for your understanding regarding used items. - Color: Blue - Color: Red - Color: Yellow - Design: Adidas logo Thank you for looking.
