Our Own Candle Warmer brand Tart Burners. Unlike our electric oil burners, our tart warmers plug directly into your wall outlet. No power cords are needed. They are perfect for use in the bathroom and kitchen. Add your favorite scented tart or place one or two drops of scented oil into the top dish and plug the warmer in to an outlet. The convenient on/off switch on the front of the warmers allows them to remain plugged it while not in use.
