Here you can buy some twisty puzzles designed by Evgeniy Grigoriev (aka grigorusha). Because they are not mass produced, these puzzles you can not buy anywhere else. Some of the puzzles were successfully picked for mass production and now can be bought at some online stores.
You pay the price cost to Shapeways (not to me!). You might also need to dye them black dyes.
You can buy some stickers for my Puzzles there:
If you don't feel like assembling the puzzle yourself, you can contact me and I will do this job for you for an additional fee (depending on the complexity) and send you the fully assembled and stickered puzzle.
