Ummm…

The orignal hand warmer was invented in 1923 by Niichi Matoba. It was called the HAKUKIN-kairo. ‘Fraid the Japanese beat us to it.

From early childhood it has never dawned on me, how it works – looking on man on ice with small rods in hand and such heaters in pockets. I think they warm up not only with these heaters )

The guy who says he invented the thing in Japan should be bitchslapped. This is a ripoff of the Jon-E handwarmer that has been sold in the US for over half a century. Here’s a link to where you can buy it at Cabellas Outfitters.

I have one of these from Sears from like the 1950’s. It’s a pretty neat gadget though, it does the trick.
