Nice fully serviced and to be cosmetically reconditioned ICE brand Super Chexx.  These are the best ones and the game to have!  No cheap home model here, this is the commercial highly desired unit.  (The pictures and video are pre-refurbishing, we will be doing soon). Order today!   These sell fast and don’t come available often.   Video showing game and explaining at; https://youtu.be/aLJup-d3EeY
