A beautiful mechanical puzzle comprised of three identical pieces, die-cast in stainless steel and weighing almost 2 pounds. 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. These pieces are cast from molten stainless steel in a ‘die’ or mold at temperatures over 2500°F.PRODUCT DETAILS 2.25" D (same as a pool ball)Die-cast stainless steel1 lb 12 ozCustom branding available upon requestABOUT THE BRANDCraighill is a design company engaged in developing, manufacturing, and selling enduring objects that ignite a sense of wonder.
