From Pluredro.com:

This is a fun, "what the heck is going on" kind of burr puzzle. If you make the first move from the assembled shape, you will know that this burr is not normal at all. It looks like an ordinary 6 board burr, but the opposite ends of the pieces that appear to be connected are not connected. Each piece has a crooked shape, and the concept of the puzzle is very similar to one of our products Crooked 6 Piece Burr. The burr makes a very unusual transformation and it is very confusing to solve despite smaller steps of a level 9 solution.

In 1998, Juno designed the first version of the Crooked 6 Board Burr in a simpler configuration consisting of three sets of mirror image pieces, but he himself never built the actual product. Decades later, he looked back on his old design and decided to produce a more challenging puzzle with the same concept. The new version can be solved without computer aids because the number of six assemblies is relatively small, but that does not mean it is easy.

Due to the nature of the puzzle design, each piece tends to move in all directions and may not seem to stand on its own. Therefore, we set two magnets in each piece, for a total of 12 magnets, to stabilize the puzzle. This modification has resulted in a much better feel when playing with the puzzle.

It was difficult to produce this puzzle with good accuracy and tolerances. A board burr puzzle requires higher durability because of the shape of the pieces, so we used our original plywood, and two elements were glued together using tongue and groove joinery to form each piece.
