A cigarette lighter is a small, portable device used to create a flame for lighting cigarettes, cigars, or other items. It typically consists of a fuel reservoir, a spark mechanism, and a nozzle. The most common types include disposable lighters and refillable ones, which can use butane or other fuels. Cigarette lighters have been around since the early 20th century and have evolved in design and functionality. They are often made from materials like metal or plastic and can feature various styles, including decorative designs. Many people also use lighters for lighting candles or starting fires in outdoor settings.
