Scentsy 20 Mini Testers Mixed Bundle #19 These sample bundles enable you to try out a variety of scents before committing to the purchase of a full 8 cube bar. 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 uses a food-grade petroleum based wax.
