This ceramic oil burner is not only functional but funky. In a unique square design the peep holes on the sides shows the flicker of the tea light candle flame. To use the oil burner, fill the dish at the top of the ceramic burner with tap water and place a few drops of your favorite Aromae Essential Oils into the water. Place a tea light candle into the bottom of the oil burner & light it with a match. As the water and essential oils evaporate, the aroma of the essential oils fill the room.
