Built to work with all of the UST lighters is the Survival Essentials Quadruple-Refined Butane. Each bottle comes with about 3.38 fl oz of butane that is made with near Zero Impurities. A lighter won't do you any good if it has no gas, and we live in a day and age where there is no need to buy another lighter, just refuel the one you have!
