XOvivo Unisex Ring Recycled and Repurposed

XOvivo ring is made with sustainable materials. See photos "with card" back and front sides. It can be adjusted a very small amount. Approximately Size 5 in photo. It is a ring for a man or woman. Aluminum and what appears to be a rubber stretch type band. So interesting! I bought ar a gallery in Saratoga Springs, N.Y.
