I bought these on Mercari, but I never had the chance to wear them and they became too small. They are corduroy, but the material is very soft and pleasant to the touch. I think they would look good on both boys and girls. There are no scuffs on the knees, and they are in very good condition. The subdued color is perfect for winter. The waist has adjustable elastic on both sides. These are genuine products sold at department stores by Sanyo Shokai.
