What are Zippo Lighter Flints used for?
hello there, Those are used in a Zippo lighter. Zippo lighters use flint and steel to ignite the lighter. There is a steel wheel which you spin that strikes the flint and causes a spark. The spark ignites the lighter fluid. The package in the picture is replacement flints for the Zippo lighter. There is a wheel at the top of the container. The wheel has a notch in it. You turn that wheel and a flint falls into the notch. As you turn the wheel more, the flint comes out of the container.
