Handmade in Japan by puzzle experts using the finest woods. The Karakul Small Box series has been produced for nearly 2 years, however the research and development for these gorgeous Karakul puzzle boxes and others stretches back over a decade.
These miniature boxes are a great introduction to Karakuri puzzle boxes (which simply means they have require a series of moves to open, an unusual 'mechanism') as they are relatively easy. They are definitely not for seasoned puzzlers or those looking for a real challenge.
Box 4 is beautifully crafted from keyaki.
