This is a compression cold therapy support for elbows and knees. Chill it in the refrigerator or a cooler box, and it's useful for icing after sports or for first aid for injuries. By inflating it with air to apply pressure, it firmly secures the affected area and enhances the cooling effect. Size: Support: Width 61cm (longest part) Length 32cm Tube: 70cm The tube is removable. Recommended by a chiropractic clinic, I used it a few times to cool my elbow after exercise. I have only used it indoors. There are no noticeable scratches or stains. Please consider this item as a used product. Thank you for looking.
