This ancient style of puzzle dates back possibly farther than any documented history of it, and is one of the oldest styles of three-dimensional puzzles we know of. An assembled burr puzzle uses six sticks of nearly-identical shape, the unique notches of each burr interlocking in a way that's hidden when the puzzle is fully assembled.
What makes this set of 25 burrs extra challenging is that, theoretically, you can pick any six burrs at random and usually find a way to interlock them together.
This set makes the perfect gift for yourself or any other avid puzzler; it comes complete with a sturdy black box that snugly houses all 25 burrs to prevent any from getting lost. Buy multiple sets to mix and match colors between them! Just make sure that the burrs you swap between sets are the same pattern.
3D printed from high quality, eco-friendly, industrially compostable PLA plastic. All puzzles will have a black box unless explicitly requested otherwise.
Each burr piece is 1/2" x 1/2" x 1 1/2" (12mm x 12mm x 36mm)
