Our tart/candle warmer combo is made of high quality ceramic and measures 4 inches in diameter and 3 1/2 inches high. The unit has a power indicator light and an on/off switch located on the cord. Our combination warmer is another great alternative for safely burning candles without flame, soot or smoke. It can be used as a candle warmer for jars up to 4 inches in width (without the ceramic dish) or as a tart/potpourri/oil warmer (with the dish). Easily fragrance any room by placing our scented soy tart melts or fragrance oils into the ceramic warming dish. When you turn it on, it will heat the contents and disperse the fragrance. The warmer and dish are made of high quality ceramic, the unit is 24 watts, and it includes an on/off switch on the cord.
