These candles, manufactured by "Country Bear Soaps and Soy Candles", are made of a soy wax botanical blend. Soy wax is a 100% vegetable by-product, not a petroleum by-product. Because of this, these candles produce 95% less smoke and soot and burn 30% - 50% longer and cooler than paraffin candles. They are non-toxic and non-carcinogenic and are easier on those suffering from asthma and allergies. Burn time is up to 80 hours.
