Lauri puzzles are made of “Crepe Rubber”, a durable rubber that won’t warp, crease or tear. The texture feels great and the pieces fit snugly. All puzzle pieces are quiet, washable, and made to last from child to child. All Lauri puzzles now come in a sturdy plastic storage tray which contains a removable assembly pattern. Lauri Foam Puzzles are the best and Lauri replaces any lost pieces for the lifetime of the puzzle.Ages 3 and up.By Lauri
