A beautiful mechanical puzzle comprising three identical pieces, die-cast in stainless steel and weighing almost 2 pounds. Initially only available in stainless steel, this all-black version features our super-durable Vapor Black finish.

Initially launched in September 2018, 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.
