Another safe alternative to burning candles with the ceramic tart or oil warmer. There is no flame, soot or smoke. Just place any scented wax tart or scented oil into this ceramic warming dish, plug it in and it will melt the wax and fragrance your room. There is an on/off switch located on the cord. Works great with any size wax tart or use a embed molds to make specialty tarts for holidays and special occasion sales. Our warmers are made of quality ceramic and they look a lot nicer than the plastic models that are sold by mass retailers. 24 watts.
