Kevin Sadler wrote about it:
“Stewart Coffin designed the involute cube is an improvement of the original convolution cube and it became another of my favourite puzzle designs. Of course Pelikan made a delightful spherical version of Convolution which I adore and keep on show in my living room – I even have permission from Mrs S because it is so beautiful. When Jakub gave me a copy of the involute ball I was absolutely delighted! The woods are beautiful and the wood turning is perfect. The disassembly is just like the original cube and a wonderful sequence but the real challenge is the reassembly After scrambling. All in all a delight to play with and a perfect addition to any collection. It is also on display in my living room.”
Note: solution is tight during part of the disassembly sequence, but overall still works well. Slight scratching from use, most notable scratches have been close up photographed. UV color fading of the pieces is noticeable upon disassembly. Original stand included.

These puzzles are extras and oddballs that have accumulated in the shop. Sometimes when we make a run of puzzles we will have a few with different woods, etc. which are too much trouble to list individually on the website. These puzzles are all in new condition and fully functional.
