Soy Pot of Fragrance Candles - The great things about soy wax is that it has excellent fragrance-holding qualities and releases the fragrance evenly throughout burning. Soybean candles burn cleaner, cooler and last longer than paraffin candles and also leave minimal wax residue. These soybean candles are in reusable glass jars with a cork lid and a natural brown paper label attached with jute twine.
