This deceivingly complex 4" diameter puzzle is guaranteed to test your spatial skills. With four possible solutions, the spherical plastic puzzle has 16 different shaped removable pieces that are held in place with strong rare earth magnets. The two-piece center core stores unassembled pieces. Each features your logo imprint on either the top or bottom piece. For a second location imprint add $.50 each. If logos are not identical, add an additional set up charge of $40. Gift boxed.
