Model #357, the third of Pyrigans machined metal mechanical puzzles.
Challenge is to open the puzzle!
It's made of T6061 aluminum with a matte anodized black finish., weighs about 13 ounces, and measures about 2″ on a side.
NOTE! It has some fairly small internal pieces that may fall out and roll away once it is unlocked so you probably want to do the final disassembly over a tray.
Warning: the internal pieces are small and could be a choking hazard for young children. I can't imagine a child opening the puzzle - it's pretty hard - but better safe than sorry so please keep the puzzle away from children under 5.
This is a limited edition of 200 puzzles with engraved serial numbers. Handassembled and tested multiple times.
