Kids' Soundproof Earmuffs I bought these for my child to use at a festival, but they only wore them once (for about 10 minutes) and didn't use them again, so I'm selling them. The logo mark has been customized. How about these for the upcoming festivals? The box has some scratches, but the earmuffs themselves have no noticeable damage. Please understand that this is a used item. Thank you for looking.
