Correct storage of puzzles prevents the loss of all important pieces. It allows completed puzzles to be shelved tidily and orderly and everybody also knows where to access the puzzles from. Shelving needs to be at varying depths to allow for peg and knob puzzles which are deeper in size as are some of the chunky style puzzles. Having puzzles stored in an easily accessible cabinet encourages frequent use. An ideal tool for preschool or kindergarten use.
