Disposable lighters are small, portable devices used to create a flame for lighting cigarettes, candles, or other items. They typically consist of a plastic casing, a fuel reservoir, and a flint ignition system. These lighters are designed for single-use or limited use, making them convenient for everyday tasks. Most disposable lighters are refillable, but many people choose to discard them once the fuel runs out. They come in various colors and designs, often featuring safety mechanisms to prevent accidental ignition. Common brands include BIC and Zippo, which are widely recognized for their reliability and ease of use.
