Karakuri Kuru Kuru Heart

Karakuri Creation Group has beautiful puzzle boxes with unique opening mechanisms and wonderful artistry.  The crafting work of Hakone & Odawara have been passed down through generations from the Edo era.  Today, craftsmen continue these traditions and explore new and interesting high quality works so that the world of the "Karakuri box" continues to evolve.

"Kuru Kuru" means "round" or "revolve".  As the name suggests, as you open the box, it will rotate and you can make the shape of a heart.
Through this motion, the lid will also open. It isn't a difficult puzzle, as it takes 4 moves to open.
