While the puzzle looks simple to make, it is anything but. There is more than meets the eye to this particular item, and I have tried to keep the price as low as possible considering the considerable amount of work it takes to make them. Crafted with some of my finest solid stock and veneers, this puzzle contains strong magnets and should be kept away from credit cards, mechanical watches, pacemakers, peacemakers, cumquats and anything else which could be adversely affected by strong magnetic fields.
