This is an interesting and difficult puzzle designed by Stewart Coffin.
7 complex pieces will assemble sequentially to form a 4x4x4 cube. This puzzle will really test your spatial relationship skills. You will likely feel like a blockhead after working hours to solve this one.... Measures about 2 3/4" cube.
Excellent fits on this puzzle make it challenging to even dis-assemble; but of course the real challenge is in the assembly.
