Good storage for unfinished puzzles. The puzzle-Mate fits well for a 1,500-piece jigsaw puzzle. The puzzle pieces do not slip, and I can sort well with the 2 additional compartments also insert the loose pieces. However, and this is the only point of criticism, not the rich 2 insert pockets for 1500 pieces. I have even organized for the spread of 1,500 parts two large Pappflächen so I can accommodate everything in storage. Otherwise, highly recommended!
