Eclipse resource trays were designed to keep all of your resource cubes organized on the table. No longer will you have to worry about someone bumping the table causing your cubes to go flying.
Includes a set of 6 clear acrylic trays with bottoms so you can lift the tray with the cubes. Total height of each tray is 6mm. Each tray is made from two pieces of laser-cut acryclic permanently bonded into a single unit.
This set of six also includes 1 piece of acrylic to use as a top when stacking all of the trays together for storage.
