This is an exclusively designed candle jar warmer created by Elanze Designs. The jar warmer is made of a thick, high quality ceramic stoneware that will last many years. It warms jar candles by simply placing them on the metal warming plate at the bottom of the inside of the warmer. Once plugged in and turned on the metal plate will heat up and slowly melt the wax, which allows the room to have a consistent but not overwhelming fragrance. This makes the candle last more than twice as long and it prevents all the mess from smoke and soot.
