Rubik-like puzzle (twisty puzzle), pentahedron shape but ghosted. 

A ghosted twisty puzzle is that where the cuts are done with each layer turned (the axis system is reoriented), so each piece is different. Because of this, no stickers are needed, but they can be added for better looks!

A set of 5 M3 screws and 5 springs is needed to build the puzzle. Typical 3x3 cube hardware can be used.
