I bought these for my daughter, but they didn't fit her, so she only wore them for a short time once. I don't think there are any noticeable stains, but everyone's perception is different, so I've marked them as having some minor wear. The size is listed as 24cm, which is a Large. I do not accept returns, so please ask any questions before purchasing. If you purchase immediately, I will assume you have no concerns about the product. Thank you.
