Size: 21.5cm My child used these in elementary school. There is a name written on the heel, but it's faint, so you could overwrite it. There are no noticeable stains, but I would like to sell these to someone who understands that they are used items. *Since they will be shipped via Yu-packet Plus, the heels will be slightly bent during shipping. There are no scuffs, and I think they are in good condition for a used item.
