These are L-size wide pants made of 100% polyester with an elastic waistband. - Size: L - Material: 100% Polyester - Design: Elastic waistband - Pockets: Yes - Color: Black Color...Black系 (Black-based) I bought these quite a while ago. There are no noticeable stains, but the area around the knees may appear slightly shiny when reflected in the light. They are easy to wear because of the elastic waistband. There is no lining. Suitable for spring, summer, and autumn. Thank you for looking.
