No numbering. REJECT x Arbiter Studio, a dtto. version glass mousepad based on REAPER, made to order. Purchased from the official store as a made-to-order item, used for about 3 months. After use, it was stored in the outer box shown in the photos. The mousepad itself is glass, so I think it's in a clean condition. In my amateur opinion, there are no noticeable scratches. The outer box has some minor scratches.
