This is a My Little Wonder collaboration Hot Wheels Trainer 110. ♡ I bought it at Birthday because it's thin, light, and seems comfortable. I wore it for about a month, but I'm selling it because my child has outgrown it. As far as I can see, there are no stains, but I would like to ask that you purchase it only if you understand that it is a used item. Thank you very much.＾＾
