These candles put out some serious heat, light, fragrance, and ambiance that is simply magical. My 16-ounce jars are filled with 14 liquid ounces of wax and will burn for days! Up to 70 to 90 hours of burn time easily. These long-lasting flames fill a dark room with ambient light and fragrance. While burning, the outside is also cool to the touch, so they are easy to transport and move as needed. I have worked diligently to make a safe, useful, beautiful, and good-smelling candle with continuous research and experimentation. My candles are backed by a 100% satisfaction guarantee.
