This folding caddy provides a stable surface for assembling your jigsaw puzzle. The caddy comes with trays that allow you to sort the pieces. If you need to put the puzzle away, fold the caddy, leave the trays inside, and secure the velcro fastenings on the edge. This allows you to store the puzzle without disassembling it. This caddy will hold most puzzles up to 1000 pieces. The manufacturer is currently out of stock on this item and they do not know when it will be available again.
