Purposely made a little smaller than most manufacturers, one child can easily carry each map, yet the knobbed puzzle pieces are large enough to make it a concrete learning experience. Vibrant, non-toxic, scratch resistant colors and a smooth lacquer finish, these puzzles have been engineered for durability as well as aesthetics. These puzzles are produced using a printing process, which allows capture of more border and coastline detail than is achieved in hand-painted versions. Moreover, a printing process allows volume production and more efficient manufacture, and you reap the cost savings. Puzzles measure 19-5/8 x 14-5/8 x 3/8” thick. Knobs are placed on the capitals of their respective countries. Unlabeled control maps (C5957) are sold separately as a set/16 (2 of each map in set, one to label which can easily be done by printing out labels on a computer and an extra blank for class copies).
