The Pyro Putty Summer Blend Fire Starter is designed thicker specifically for warmer temperatures, but no matter if the weather is hot, cold, wet, or windy, you can easily light it up. You can make a 4 to 6-inch flame with just one nickel size piece of putty and it will burn 6 to 10 minutes. Because you are using just nickel size amounts at a time, 2 oz of putty can last you up to 50 fires. On top of its primary use for easily making a fire, Pyro Putty has other unique uses as well. You can expose Pyro Putty to UV light to make it glow in the dark and mark trails. And, because it is waterproof, you can rub it on a tent to repair leaks or your shoes to help waterproof them.FeaturesWaterproof and weather-resistant Quick ignitionCan be used to waterproof shoes and tentsGlows in the dark
