Single Flame: The insert with single gas flame is suitable for all smoking products except cigars and of course for all other uses of lighters -> candle, grill, campfire etc.
 
Stinker! <- There are said to be people who don't like classic Zippos because of the smell of the gasoline. Personally I cannot understand that, I like it very much. But, everybody is different.
 
Now finally Zippo has brought out its own butane gas cartridges. And these parts are really great! High quality workmanship, matching the design of the gas insert and a perfect fit. One gas filling lasts for a few weeks, refilling is easy and safe.
