This Limited Edition Puzzle is being sold from a private collection. Designed by Lucie Pauwels, the Rotacube Puzzle measures: 80 mm x 64 mm x 64 mm. and was distributed by Pelikan Puzzles. Crafted in American Walnut, Mahagony, Maple, Wenge and Acacia. The designer describes his inspiration by the following: “One day I was playing with 2 spirals that form a cube, I added a few blocks on one end of both spirals and took a few off on the other end. Then I was thinking it would be impossible to take both spirals apart. To my surprise it worked, and the movements needed are very interesting. It took me a while to put it back together. Then I added pieces to fill up the puzzle, using some half-cubes and found a good interlocking system. I am very pleased with this puzzle and happy to see the beautiful version made by Pelikan.” The solution is NOT included.
