According to the official Nike size chart, kids' size M is approximately for heights 128cm-137cm (ages 8-10). Let's say 130cm. This is a personal inspection, but there are no stains. There are no noticeable scratches or stains, so the condition of the item is listed as "no noticeable scratches or stains," but subjective opinions vary. Personally, I think it can still be used, but there is some slight fuzzing, so it's not completely without a used feel. Please refrain from purchasing if you tend to complain about a used feel after buying something that is not new. I am being sensitive. Sorry. Please refer to the photos carefully and make your purchase only if you are satisfied. Packaging may use recycled materials.
