This mini lighter is convenient to carry anywhere(37.3g only),no need to refill kerosene or gas,perfect for wilderness activities,camping or other outdoor activities. It features high quality metal body and well-built interior structure and NO FLAME, just spark Usuage:just strike the attached flint wheel to create sparks, which are caught on a charred cotton rope, that has been partially withdrawn from a metal tube housing. This was typically used for lighting cigarettes which does not require a flame to accomplish.Once an ember is generated, it is windproof, and is extinguished by retracting the cord back inside the tube and an attached lid snuffs it out. Note:With a new rope lighter, burn the end of the rope before using it with the flint. The end must be blackened for the spark to catch.
