For the product to work as intended, you need to add chemically pure gasoline (available at pharmacies) to the container the first time! Forget about having matches everywhere and forget about having to take care of burnt-out matches or empty lighters! Here is the Waterproof Eternal Match that can be used up to 10,000 times! The genius of the fire steel lies in its ability to work in all weathers and provide quick, safe ignitions even when the weather and wind are against you. The steel is extremely durable and can be used several thousand times before it wears out. The "match" inside the fire steel has a wick so that it works like a match that can be used over and over again. If the wick burns down, it is easy to pull more wick out of the match. Scrape the match (which has a piece of metal on the top) against the side of the fire steel to get a spark. The sparks from the steel are also very large to easily light candles, bonfires or gas!
