Product Description

Burr Puzzle or Kongming lock, is also called Eight-Diagram lock and Luban lock. It is originated from the mortise and tenon structure of ancient Chinese architecture. The meshing of the concave and convex parts inside this three-dimensional splicing device is very skillful. It does not require nails or ropes, and is completely supported by the connection of its own structure. It can stand up like a piece of paper by folding it in half. It shows a seemingly simple but condensed extraordinary wisdom, and greatly reflects the wisdom and spirit of ancient people.
