A beautiful mechanical puzzle comprised of three identical pieces, die-cast in stainless steel and weighing almost 2 pounds. Until now the Venn Puzzle has only been available in stainless steel, but this limited release features super-durable Carbon Black finish on a small number of units.
The Venn Puzzle is a surprisingly difficult dexterity challenge and an intriguing addition to your desk, shelf, or coffee table. The assembled puzzle creates a perfect sphere — so each piece makes up one-third of the sphere by volume. While simple in concept, reassembling these three surprisingly heavy pieces of stainless steel is deceptively complicated. Once you've mastered it, the visual and tactile appeal hold fast long after the initial challenge has been vanquished.
These pieces are cast from molten stainless steel in a ‘die’ or mold at temperatures over 2500°F.
