These are 1 meter fireproof blankets. If there is a small fire, take it out of your pocket, turn it over and throw it on a small fire. I saw him put out the grill fire. It's usually around 400-500 degrees. I checked the blankets with a lighter. You wouldn't burn out. (PERFECT!) So I gave one to each of my neighbors and a few friends. I bought a few more and gave them to the local museum.
