Used about twice. There are no noticeable stains or scratches. The main body is natural rubber, and the Velcro is nylon. Size M-L (waist approximately 90-110 cm, length approximately 95.5 cm) The printing on the box peeled off when removing the sticker (photo 2). To adjust the thickness, I will ship it without the box (the box will be folded and included). Please refrain from purchasing if you are concerned about minor details.
