A BIC lighter is a small, portable device that produces a flame for lighting cigarettes, candles, or other objects. It consists of a fuel reservoir, a valve, a flint, and a striking wheel. To operate a BIC lighter, the user turns the valve to open the fuel flow, then strikes the flint against the striking wheel to create a spark. The spark ignites the fuel, producing a flame.
BIC lighters are popular because they are inexpensive, reliable, and easy to use. They are also relatively safe, as the flame is contained within the lighter and the fuel reservoir is sealed. BIC lighters are available in a variety of colors and styles, making them a popular choice for both personal and commercial use.
