Colibri Premium Butane is one of the cleanest available for your lighter. This butane is produced to the exacting standards required by the high performance jet (torch) lighters introduced to the world in the mid-1980s. Colibri butane is processed in world-class refineries and canned in only the cleanest environment possible, resulting in fuel so pure -less than 6 parts per million!- that it does not require repeated filtering to remove the unwanted matter and contaminants that affect the performance of your lighters, and adulterate the flavor of your premium cigar or tobacco. Colibri Premium Butane is developed to reduce the number of contaminants that cause clogged burner valves, misfires and malfunctions—and to safeguard against costly repairs.
