This puzzle-stowing kit brings portability to puzzle making by giving you a way to securely store unfinished puzzles. Instead of leaving your in-progress puzzle out, you can use this handy kit to keep pieces organized and in place. With a mat measuring an ample 59 by 39 inches (L x W), the Giant Stow & Go lives up to its name. This extra-large mat fits puzzles with 1,000 to 3,000 pieces, so you can use it for larger puzzles that take longer to complete. For ages 6 and up. WARNING: CHOKING HAZARD – Small Parts. Not for children under 3yrs.
