These are made out of Glass, with a glass dish.  They all come with a light bulb and have a dimmer switch on them making them go from low to high.  
They will make a great night light if you have a dark room or hallway.  If you purchase on of my warmers you will have your choice to recieve a bag of candle melts also.  
What good is a new warmer if you have nothing to use in it.  You will only need to put one piece of my melts in your warmer.  They will last for a few days.
