This unique Pyramid Puzzle is great for the blind or anyone who appreciates a fun brainteaser. It is not a difficult puzzle, although there is one small irregularity to beware of. When assembled, the 3-inch Pyramid Puzzle sits in a carved wooden base. It comes with a protective clear plastic cover that keeps it from getting knocked over without obstructing your view of the smooth, beautifully stained wood. Total Dimensions: Approximately 4 in. by 4 in. by 3-1/2 in.
