Butane is a colorless gas with a faint petroleum-like odor. For transportation it may be stenched. It is shipped as a liquefied gas under its vapor pressure. Contact with the liquid can cause frostbite.
Premium butane is required to ensure optimum performance of your lighter. Lighters require the cleanest butane available at a pressure of 45 psi. Recommended premium butane brands (Colibri, Nibo, Prometheus, any triple refined butane) are packaged in 10-13 oz. cans with a metal fill tip nozzle.
