If you light your smoke with this Zippo you are likely to get a mini bullet in the face. This Zippo is packing a miniature gun inside that actually fires. Those copper-cased 6mm cartridges will be fired out of a barrel, in place of the usual wick.
Just roll the flint striking wheel and it acts as the trigger. Too bad this isn’t an official Zippo product, then again, if it was, there would be a lot of smokers shooting themselves in the face.
