Mesh material, free-size wrist support with Velcro. For the right hand. Although the size isn't specified, I bought it for a woman, so I think it's S-M size. I bought it as free size. It's adjustable with Velcro. I've used it for about a week, and the support stiffness hasn't deteriorated, and there are no pills, so I think it's relatively clean. - Brand: Mueller R - For right hand - Color: Black - Features: Mesh material - Size: Free size - Fastener: Velcro Thank you for viewing.
