The traditional portfolio-style Caddy is back and better than ever with this new design. This Caddy will hold puzzles up to 1000 pieces in size, with maximum dimensions of 20" x 27". The rigid outer surface protects your puzzle while you store it. Internal trays let you sort the puzzle pieces out to help with assembly. Begin assembly inside the caddy and when you are ready to stop, simply fold it up and slide it under a bed or stand it in a closet.
