Here it is, the most challenging puzzle of all, both because of the difficulty in finding where the pieces go as well as having the dexterity to hold it all together. Only one solution, but it is worth the challenge because of the great satisfaction of sliding that last piece in and seeing the beautiful cube you have created. Then hand it to a friend and see how much fun they have trying to take it apart. Dimensions: 2.5"x2.5"x2.5"
