These warmers can be used to up warm your favorite candle. They warm up any type of jar candle. Just pick your favorite scented candle and turn on the switch an leave it for awhile. You won't have to worry about having a burning candle with a flame. Please make sure you put the warmer out of reach of children as it can be pulled and spilled easily. Also do not leave the candle warmer on when you leave your home or go to sleep for your own safety and the safety of your loved ones.
