This puzzle is not like other puzzles you may have seen before... It is difficult to take apart, but even more to put together. Even when you have seen how the pieces are constructed, it is not obvious how to reassemble it.
Materials: A high-quality product made from precision machined polished Aluminium. The puzzle is engraved with Wil's signature so you know it's an original. This current manufactured batch has brass end pins which are different from the steel pins Wil previously used in the puzzle.
