These items are made with new fabric that has been pre-washed. They are 100% cotton. They should fit those with shoe sizes around 24-25 cm. The fit doesn't need to be as precise as shoe sizes. The width is 9.5 cm. They can be washed at home and worn repeatedly. They will become more comfortable with wear. As they are handmade, there may be slight variations. The color impression may vary slightly depending on your monitor. Thank you for your understanding.
