In 2012 Tony Fisher created hand-made puzzle samples for this series. With the help of Evgeniy, the puzzle design drawings were made into solid works files. On and off mould drawings and production issues have caused this 6 year delay. Finally the product has been able to be mass produced to the quality you would expect.
The Overlapping Cube and Mini 5x5x5 Ball are the main members of this family series. With these 2 puzzles, you can make quite a lot of variations. Currently available only in the stickerless version, this puzzle is great for any collection!
