Plantlife Aromatherapy Candles are made with four plant waxes which deliver a cleaner and better performance than Soy based candles. 100% Pure Essential Oils are used to provide an Aromatherapy benefit by entering the body through inhalation. Unlike petroleum based candles, the Plantlife cotton wick burns clean with no black smoke. Plantlife Candles are synthetic-free...fragrant to the very end!
