Duraflame Crackleflame fire logs are a great, easy way to have a fire when camping or at home. No dry wood available? Campsite doesn't allow firewood gathering? Can't get traditional firewood to light? This product is the answer to your problems! Simply set the wrapper on fire with a single match and you're on your way to a warm, comforting fire. My husband and I bought a 6-pack of logs to burn in our fireplace and backyard. It's perfectly safe and easy to contain, and I didn't worry about the flames going too high. Although this is not specifically a low-spark log, there were very few sparks. We used it in our metal fire pit and it gave out a pleasant amount of heat for over three hours. Cleanup is easy.
