I have most of the difficult Hanayama puzzles and struggle to find cool new puzzles that put well together. It fits these two accounts. It's fairly simple, a 2 or 3 minute puzzle at best, but it's a really nice piece of machinery and well put together. I have a much more complex puzzle box, but it's not as creative as this mechanism. Put a challenging puzzle in the box and give it to a friend for a laugh. :d Has a nice handmade feel.
