I had five of these racks before they started getting sold in mass quantities. I recently found a different storage option for the items I was using these for, and I don't think I need them any longer. These are advertised as the 50mm size chip racks. The bottom picture shows a rack holding 49mm dealer buttons. I have tried using them to hold a bounty puck that measures just under 51mm and they don't quite fit. So 50mm seems to be very accurate. I would prefer to sell these together. Price is $25 for the racks plus $15 MFRB shipping (in the USA). Dibs sale.
