A BIC lighter is a small, portable device that produces a flame for lighting cigarettes, candles, or other small objects. It consists of a fuel reservoir, a valve, and a flint striker. The fuel reservoir is usually filled with butane gas, which is released through the valve when the striker is ignited. The flame is then produced by the ignition of the butane gas with the flint.
BIC lighters are very popular because they are inexpensive, reliable, and easy to use. They are also relatively safe, as they have a number of safety features to prevent accidental ignition. BIC lighters are available in a variety of colors and styles, making them a popular choice for both men and women.
