This Maxijet model has a novel form that sets it apart from conventional S.T.Dupont lighters. When you press the push bar, a blue jet flame (flame) will rise. Powerful jet flame ignites smoothly under any conditions. The strong flame has received great praise from cigar lovers. Slim, elegant and contemporary design. Easy to operate and ergonomically designed. You can check the remaining amount of gas from the window. Line 2 and Gatsby models feature DuPont's unique opening and closing sounds. The sound varies depending on the individual lighter, and the sound quality itself changes with use. Please note that we cannot adjust or repair the sound of the lighter after it has been sold.
