Packed with technology, the Maxijet lighter features a powerful, wind-resistant, torch flame suitable for all conditions. Features Dupont's patented Piezo system with an adjustable blue torch flame. Longer trigger providing better ergonomics. Features Dupont's inversion safety feature, preventing the lighter from igniting when in the downward position. The flame is adjustable at the base of the lighter and is refillable using S.T. Dupont's black bottle gas (sku #000430). Improved, wider air inlet allows access to a protection grid that prevents impurities from getting inside the mechanism and two textile strips of active charcoal help to filter other impurities.
