A lighter is a portable device that produces a flame, typically used to ignite cigarettes, candles, or other small objects. Lighters come in a variety of shapes and sizes, and can be fueled by butane, propane, or other flammable liquids or gases.
Lighters are an essential tool for smokers, and can also be useful for a variety of other purposes, such as lighting campfires, candles, or fireworks. They are also relatively inexpensive and easy to use, making them a popular choice for people of all ages.
