The Four-Piece Serially Interlocking Cube is another great design by Stewart T. Coffin (STC-93). These variations are crafted by the Mercury Woodworker.
It's sequential. It interlocks. It fits perfectly in your hands. What more could you ask for in a simple yet elegant puzzle?
Approx. dimensions are 5.7cm x 5.7cm x 5.7cm (~2-1/4" x ~2-1/4" x ~2-1/4").
(The old poker dice are for scale only, not included with the puzzle.)
