This Obsidian pluggable warmer from RC Willey features marbled white swirls that flow through the black hand-blown glass to gently highlight the glow of this Candle Warmers fragrance warmer. Add your favorite scented wax melts to the screw top styled dish. The soft glow of the halogen bulb creates the ambiance and fragrance of a lit candle, without the flame, soot, or other pollutants. Simply add wax melts to the dish, turn it on, and enjoy your favorite fragrance as it spreads through your room. Wax melts sold separately.
