Colibri Premium Butane is the cleanest butane available. Colibri is produced to the exacting standards required by high performance jet-flame lighters—a technology Colibri introduced to the world over 35 years ago. Their 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 filterings to remove the unwanted matter and contaminants that affect the performance of your lighters, and affect the flavor of your premium cigar and/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. The 300 ml canister is also fitted with five removable adapter nozzles in the cap.
