Thank you for viewing. I've only worn these once or twice for a short time, so they are very clean with no scratches or stains. They are made of a black, thin ribbed fabric. They can be worn for both a clean and casual look. The size is 36, which is equivalent to 23cm in Japan, but they feel a bit large. I purchased them from the H&M official online store for around 3000 yen. Thank you for your understanding regarding used items. Color: Black系 (Black-based) Toe: Round toe Stains, tears, odors, etc.: None
