The Void – Edge Only Cube is manufactured from a high quality black plastic.  The object of this puzzle is to scramble up all 6 sides and then return it so that each face only has one color on it. This puzzle is unique because there is no core at all, you can see right through it as the puzzle rotates around the frame.  Also, this puzzle is made up of only edges, so every piece can change places with any other piece.  This is one of many great puzzles from LanLan.
