There are 200 pieces in the box. I meant to make all sorts of puzzle prototypes out of them, but never really got around to it. Weighs 1 lb 3 oz before packing.

While not technically a puzzle, if you need something to occupy your hands while your mind chews on a problem, this is your best friend. Precision cut and h...

HexyHex is a wire frame that flexes somewhat like a flexigon, making a few interesting shapes but not really a puzzle in any sense at all. It has an original price tag for L1.95. I'm guessing it's from the 1960's or thereabouts.
