The waterproof case that the matches come in I recently aquired a box of UCO stormproof matches that I was planning on using for lighting solid fuel tablets and for other camping fires. Since then I have used them to light solid fuel tablets. I have also tested the water-proofness of them. They worked great and I figured out that as long as there is enough of the orange portion of the match left, the match can't be put out by water or wind. After being dunked underwater, the match does sputter but it still is lit. The case that the matches come in is very protective and is waterproof. The case comes with 25 matches and 3 strikers. The case fits 25 matches, give or take. These are the right choice is you want to definitely make a fire. These matches are the most reliable method of ignition I have found so far because they don't go out until, at the very least, the orange portion of the match is burned through. Both regular matches and regular lighters go out easily with wind
