This is such a cool Aromatherapy Diffuser. Its made out of terra cotta, and you put a tea light inside it, and fill the top with about 10 drops of the purifying oil. Then light the tea light and enjoy the relaxing effects of the scent wafting through the room. It is a natural air freshener kit that will make any room smell crisp and clean. Using this combo is a great way to reap the benefits of essential oils and their aromas. The terra cotta diffuser and oils are both all natural. Be careful though with the diffuser after the tea light is lit because it does get quite warm.
