I keep the cotton balls that my wife uses to soak up the wax from her scensy melted wax pot. Place them in a ziplock and you are good. I have used a ferro rod on them and they burn just fine.In addition to a ferro rod, I keep a sealed container of cottonballs which have been soaked in petroleum jelly. A ferro rod isn't any good if you cant find something dry to ignite. These cottonballs light super easily and stay lit for quite a while
