Refillable lighters are portable devices designed to ignite a flame for various uses, such as lighting cigarettes, candles, or campfires. Unlike disposable lighters, which are thrown away after use, refillable lighters can be filled with lighter fluid or gas, making them more environmentally friendly and cost-effective over time. These lighters come in various styles, including butane lighters, torch lighters, and zippo lighters, each offering different flame types and features. Refillable lighters are popular among smokers and outdoor enthusiasts due to their durability and the ability to replace fuel as needed, ensuring a reliable source of fire.
