Sounds like a sound idea but, I have found or stored Bics (only) and have never found one out of gas that I hadnt ran it out by myself.seems like other butane lighters are useless.we also keep on hand bic sparkies,the long lighters for fireplace/bbq lighting,I used one the other day that was in the package for at least 3 years.and you could see that the level was still high in the reservoir.also, zippos,matches and other goods are kept by us as well.
