Electric tart warmers with soy tarts are a safe alternative to burning candles. There is no flame, soot or smoke. This combo warmer can be used without the ceramic dish as a candle warmer that fits any jar up to 4″ wide, or with the ceramic dish as a tart/potpourri/oil warmer. Just place any scented wax tart, scented oil or votive (remove the wick first) into the ceramic warming dish, plug it in and it heat the contents of the dish to release fragrance into the room. You can also remove the warming dish and place a jar candle directly onto the heating surface (works great as a coffee/tea warmer, too!). These warmers are made of quality ceramic and they look great with any decor. These have an on/off switch located on the cord, and a power indicator light on the base of the warmer. 24 watts.
