The flame height must be adjusted again to the desired level, since the butane pressure in the fuel tank decreases after a period of operation.

Note Lighter is shipped WITHOUT butane due to DOT and USPS Safety Regulations, please fill with butane fuel before use. Do not turn on the lighter on the highest flame unless necessary. Due to the high pressure, the flame does not go out immediately after releasing the ignition button, which can cause accidents and dangers. At the same time, it will also affect the life of the lighter! The lighter will not ignite at the lowest setting because there is no butane pressure.
