A wickless candle is a highly fragrant wax bar that is warmed to release fragrance into the air. Because the wax is gently warmed rather than burned, it can hold more fragrance oil than a traditional candle. And, because there is no flame, there is no smoke, soot, or lead. Scentsy wickless candles are a safer alternative to traditional candles. Scentsy's beautiful warmers house a low-watt light bulb that slowly melts the Scentsy candle bar, filling your home with one of more than 80 distinctive and long-lasting scents. The combination of a Scentsy warmer with a Scentsy Bar is known as a Scentsy System.
