Love Story Scentsy Bar Wickless Candle Tart Warmer Wax 3.2 Fl Oz, 8 Squares 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. One Scentsy Bar comes in a clamshell with eight break-a-part cubes. Choose your favorite candle bar scent, break off one or two cubes and place in warmer.c Scentsy uses a food-grade petroleum based wax.
