This storage folder supposed to fit 24 jigsaw puzzle,but if you go back to back you can fit 48 so that there is an image on both sides when flipping through. But it gets heavy pretty quick if you load 48 sets puzzles. Kindly Notice: 1,Please mearsure your complete puzzles when insert it to the puzzles sleeves. 2,This grand albums capacity is also suitable for part of brands' 1500pcs puzzles. 3,Suggest to flat storage the full puzzles folder. It will tilt if upright storage because weight will increase when puzzles increase.
