The combination of wood and metal provides the puzzle a unique appearance. The wood is natural and the different colors of the pieces are because different kinds of wood are used, which makes it very special to have as part of your collection.
The name of the puzzle in English is "Lock With Wood", and the challenge here is to remove the wooden ring from the rest of the puzzle. You will need to understand the internal mechanism in order to solve the puzzle.
