Our Illumination Fragrance Warmer is one like no other. Designed to fill a space with stunning light effects, this piece is truly a show stopper. We all love our homes to smell fresh! Some of us like to utilize soy wax melts and others Essential Oils. Our Fragrance Warmers are ideal for both. For Use With Essential Oils : Add a safe amount of water to the cavity above and then 4-6 drops of your favourite oil(s). Make sure to set back away from little hands or paws!
