Hanayama Cast Puzzles are well-crafted metal puzzles that stand out not only for their exceptional quality but also for their extraordinary and high-quality design. The name "Cast Puzzle" comes from the English word "to cast," which means to mold metal.

The challenge of this intricate metal puzzle is to separate the pieces and then reassemble them.

The two intertwined pieces are identically shaped and very simple. They resemble hooks used for hanging items. The pieces can be separated and reconnected in a fascinating and magical sequence of movements.

This Cast Puzzle, which is simple yet mysterious and functions like a disentanglement puzzle, was created by Finnish designer Vesa Timonen. The theme of this puzzle is hooks.
