We have tons of kids puzzles and before we got one of these puzzle storage cases, they were everywhere. Now we have two of these and the kids know just where to put the puzzles back - and fewer lost pieces! Each Storage Case holds twelve 9x12 puzzles. I've seen these in a bunch of places. Melissa & Doug make two versions: Natural Wood and Primary Colors. Organize that playroom before everyone is stuck inside for the winter! I highly recommend them!
