Our candle warmers work in the following manner: A candle, or scented tart (and some times fragrance oils) are placed onto a heating plate, or melting dish. The plate warms by using electricity or in some cases a flame (tea light candle warmers), which warms and melts the candle tart or oil. This releases the scent, which fills the room, eliminating odors and adding candle scent to the area. 2 in 1 Candle Warmer includes a dish that can be used to melt scented candle tarts or scented oil. Dish can be removed to use the warmer with a jar candle. Includes 6 ft power cord, on/off switch and indicator light on front of the warmer. UL Listed for safety.
