Butane canisters are small, pressurized containers filled with butane, a type of hydrocarbon gas. They are commonly used as fuel for portable stoves, lighters, and camping equipment. These canisters are designed to be lightweight and easy to transport, making them popular for outdoor activities like hiking and camping. When using butane canisters, it's important to follow safety guidelines. They should be stored in a cool, dry place and kept away from direct sunlight or heat sources. Proper handling ensures that the canisters function effectively and reduces the risk of accidents or leaks.
