This hand warmer involves some kind of fuel as there was a funnel included in the original packaging. Not sure how it works. Leave a comment if you know how it works.
I used to use this in the 80’s. First you open the hand warmer, then take out the inner part, put the funnel into the inner circle, fill it with fuel, put back the inner part and light the warmer with lighter comes with the package. Then cover the warmer and enjoy the heat.
