An 8.5″ x 8.5″ square tray uses a cork-facing surface over an MDF core, with recessed sections and raised edges for coaster storage or serving. Cork brings lightness, water resistance and a warm wipeable surface that helps protect tables from everyday moisture. The MDF core gives the tray structure. The format turns loose coasters into a table system for desks, meeting rooms, pantry counters and client gifts.
