These firelighters are all-natural fine wood shavings spun & dipped in untreated wax, the wood is made from renewable, natural wood waste. They have a strong, long burn time & make fire lighting an easy pleasure. They are great for using in all wood burning stoves, fireplaces & charcoal grill with no nasty kerosene smell & safe to handle. Simply place one or two flamers onto the fire grate & place kindling wood on top making a wigwam shape.
