100% Soy Candle. 12 oz. Jar scented with essential and/or fragrance oils. Mystery Candles are layered with different scents so that as they burn, the aroma will change with the corresponding scent. The various fragrances used are not documented, hence the mystery. This candle has a 100 hour guaranteed burn, but has lasted up to 115 hours on many occasions. Initial burn time 3 hours.
