The Coffin’s Four Piece Cube is very well made out of white oak and finished with an oil finish to give it a smooth touch and allows the pieces to slide smoothly but remain snug in the solved position.

The object of the puzzle is of course to take it apart and put it together again. This is an interlocking cube after all, and the pieces fit so very well that I took a wee bit of time to find the first piece that moves. After that, it was a matter of tugging at the remaining pieces for them to come apart. Putting it back was not so easy if you scramble the pieces and happen to forget the orientation and positioning of each piece.
