The Venn is a beautiful mechanical puzzle comprised of three identical pieces, die-cast in stainless steel and weighing almost 1 KG.
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 at temperatures over 1300C. Accompanied by a small brass display stand.
