MUJI. Black socks that stretch well overall, size 23-25cm, made by MUJI. - Color: Black - Size: 23-25cm - Brand: MUJI The soft cotton weave makes the socks feel fluffy when worn. There is no tightness. Because it's soft cotton, hand washing is recommended, but I put them in a laundry net and wash them normally. I haven't had them for a month yet, so I don't know how durable they are compared to regular socks. I'm selling some of the items I bought in a bulk purchase. Thank you for looking.
