Our top-down warming technology provides the look and fragrance of a lit candle without the flame, soot and smoke. A large pool of melted wax at the top of the candle releases a cleaner, stronger fragrance that lasts up to twice as long compared to burning a candle. Accommodates most jar candles. A variety of styles are available, making them a choice accessory for any room. We recommend lamps and lanterns for melting larger candles. Bottom up warmers are not effective at warming larger candles quickly.
