Pluggable Fragrance Warmer glows when lit. Can be used in both vertical and horizontal outlets by twisting the plug base, making them ideal above counter outlets in small rooms and spaces. Wax products from Candle Warmer are 100% paraffin wax that holds more fragrance and lasts longer compared to scented gels, oils, or sprays. The soft glow of the halogen bulb creates the ambiance and fragrance of a lit candle, without flame, soot, or other pollutants. Elegant home decor is the focus of every Candle Warmers product, and each is made to complement your personal taste.
