I have no idea what that means LMAO. Many years ago, long before I ever imagined I'd spend some time in the HVAC/R trade, some of us were too stupid to know that butane reaches atmospheric pressure at close to the freezing point of water. This means, of course, if you leave 'em in your Kold Kar, the damn things don't work, unless you warm 'em up.
I don't smoke, but used to keep some around for emergency stuff and "when ya need" fire." I finally went back to matches LMAO
