The product is made from new fabric that has been pre-shrunk. It is 100% cotton. It should fit those with shoe sizes around 27-28 cm. It doesn't need to be an exact fit like shoe sizes. The width is 10 cm. It can be washed at home and worn repeatedly. It will become more comfortable with wear. As it is handmade, there may be slight variations. The color impression may differ slightly depending on the monitor. Thank you for your understanding.
