This clever kit combines a simple puzzle sorter, puzzle board and frame. Slot the interlinking cardboard pieces into the box base, to give you different "sorting" sections. Sort your puzzle pieces, finding the edge pieces first and then sorting by colour. Assemble the jigsaw cut puzzle board and build your puzzle. When your puzzle is complete, pop the printed frame on top and secure with the plastic clips. Now everything is held securely and your puzzle is ready to display! When you want to build another jigsaw, remove the plastic clips and frame, scramble the puzzle into its original box and start on your next design! Note this only fits Ravensburger 100-300pc XXL puzzles (finished size 49.3 x 36.2cm). Puzzle shown on box top is not included.
