Lighters are small devices used to create a flame, making it easy to ignite things like candles, cigarettes, or campfires. They typically contain a fuel source, such as butane, and a mechanism to produce a spark. Lighters come in various styles, including disposable ones and refillable models, and are often designed to be portable and user-friendly. Many people carry lighters for practical reasons, but they can also be decorative. Some lighters feature unique designs or artwork, making them popular collectibles. Additionally, lighters are often associated with activities like smoking or outdoor camping, where having a reliable flame is essential.
