This is no ordinary lighter , it comes in a key chain form , but lights like a match , it uses lighter fluid (zippo kind) .

The Bezel like cap unscrews , and can be striked at the side to light .

and conveniently put back in the screw hole after use and it is ready for use again .

Genuine collectors item
