OMG Good to know. Because I'm dumb enough to purposefully clean my torch lighters with ISO. Will be that much more watchful of cracks, etc because my lighters do get jumbled around in my dry bag. I do own a silver Jetline Tempo which looks like the one in the pic, but with the Jetline logo. A somewhat more ordinary looking cigar lighter that will get more use for about town and the arsenal of torch lighters for long trips.
