The "Lean-Burn" system is the latest technological
advancement in lighter engineering. A Revolutionary lighter for the 21st
century. The "Lean-Burn" system generates a stable combustion by setting
the catalyzer in the middle of the internal burner cylinder which in turn,
generates a secondary gas combustion. This mechanical enhancement results
in two revolutionary achievements. First, it drastically reduces the gas
consumption rate of a lighter by 50%. For example, it enables a user to
smoke 10 cigars a day or 20 cigarettes a day for 60 - 120 days without
refilling. Second, it allows the lighter to work in high altitude places,
where the amount of oxygen is limited. High-Altitude Proof
