Purchased last year at Nishimatsuya and worn several times when going out. This is a set of 3 pairs of warm baby socks. I think they will be useful in the cold season♪ There are no noticeable stains and they are relatively clean, but please purchase only if you understand that they are items that have been worn by a child and stored at home. Home cleaned. Please understand minor things like folding wrinkles when shipping. Thank you very much.
