Thank you for viewing. I am selling this because I purchased the wrong size. I bought this as a box-damaged item, so as you can see in the photos, there is a scratch on the side of the box. It is a new, unopened item. This is a hard-type supporter that firmly supports the knee during light exercise. - Brand: SIGMAX - Type: Hard type - Application: Knee supporter - Features: Firmly supports the knee of the wearer during light exercise - Size: S - For both left and right knees: Left and right compatible Thank you.
