I found these while cleaning out my parents' house, in a storage box. They are unused, but have been stored for a long time, so I don't know the details. Reasons for the condition: ① I don't know the size. Foot size: Approximately 15cm Length: Approximately 57cm Waist: Approximately 19cm (Measured flat, unstretched) Please check with your child's tights and consider purchasing. ② Due to long-term storage, they have a mothball smell. If you are concerned, please wash them once. ③ There are some stains on the striped soles (photo 6). Otherwise, I think they are in good condition without any noticeable stains. Please refrain from purchasing if you are sensitive to items that have been stored at home for a long time. This is a set of 3 pairs. Please understand. Please consider purchasing.
