500 and 1000 piece puzzles are the most popular of puzzle sizes. Not a one sitting project for most puzzles so luckily for us, Schmidt Spiele has developed this convenient puzzle pad for 1000 piece puzzles. It makes it easy to construct the puzzle and move it out of the way when necessary. The mat is made of felt and the inner tube for rolling is made of plastic (nothing to pop!) Velcro straps hold it shut when in use. The pad measures 95 cm x 50 cm or for those of us more used to inches, that translates to 37.4" x 19.68". Please verify your puzzle is the appropriate size to fit both your puzzle and your table when purchasing. The puzzle pad is made in Germany.
