The campfire fire starteris a fire starter designed for outdoor survival gear, the size varies they are cardboard wrapped in twine dipped in wax they do have matches that have also been dipped and wax to help with waterproofing, so you might have to clean off the head of the match before striking it. these last anywhere from 5 to 15 minutes, I have used these numerous times myself with no problem. this will come in a plastic container with a strike sticker on it and a free lighter
