These are the 1000 and 2000 piece 'Pure Hell' jigsaw puzzles manufactured by Beverly of Japan (available for ~$20 - $34 on Amazon). The puzzles,which are made up entirely of micro-sized pieces for extra difficulty, are available in pure white or black and degree a scant 26 x 38cm (~10 x 15-inches) for the 1000 piecer and 40 x 50cm (~16 x 20-inches) for the 2000. It says they're recommended for ages three and up although I can't imagine a three year old doing anything but eating the pieces. Same goes for my dog. Translated item description:
Please effect beginners Never buy. The world's smallest 2000 piece puzzle. You must have remarkable spirit! - Difficult!
- Small!
- Please effect beginners Never buy.
So they're for ages three and up but not for beginnners, and got it. You know I remember when I was in my early teens I was super into jigsaw puzzles and bought one of the "world's most difficult" at the time and it was a double-sided circle puzzle with the same solid blue on both sides. It was DIFFICULT. I wonder whatever happened to that puzzle. "You set it on fire." I burnt that impossible bastard to a crisp!
sustain going for one more shot.
