Tetra Puzzle — Stainless Steel

Four Pieces. One Tetrahedron. Good Luck.

The Tetra Puzzle is four precision-machined stainless steel pieces that assemble into a perfect tetrahedron — and disassemble into a frustrating pile of parts the moment you lose track of the solution. Compact, dense, and satisfying to hold. The kind of object that sits on your desk and distracts you productively.

Designed and made in Brooklyn. Difficult in the best possible way. Browse more in our everyday carry collection or check out the Craighill Andromeda Puzzle and Venn Puzzle for more mechanical challenges.
