|The Japanese company Hanayama have been making a range of cast metal puzzles for over a quarter of a century now. The design of their puzzles is amazing, as is the craftmanship with which they are made. Hanayama make a wide range of cast puzzles. We have just selected a few of our favourites to offer here in the Grand Illusions Toy Shop.MOBIUS is Level 4 Difficulty (i.e. reasonably difficult). It comes in a smart presentation box. The challenge is to separate the two pieces, and then to put the puzzle back together again.These puzzles do not come with a solution. However if you visit the distributor website at http://www.eureka-puzzle.eu/eureka/index.php?/all-cast-puzzle-solutions.html and enter the complete barcode found on the box your puzzle came in, you will be able to access the solution.
