Presented in our signature Italian perfume bottle with glass stopper, each 7.4 oz. AirEssence? includes a hand-made antiqued mirrored tray, which adds a special luxurious finishing touch and protects whatever surface upon which it is placed. Because we use only the finest essential oils and add no alcohol, you can expect to enjoy our AirEssence? for up to a year. We're very proud that Agraria AirEssence? is recognized as the longest lasting reed diffuser on the market. Bitter Orange is a complex & subtle blend that permeates the air with additive waves of clove, the zest of bitter orange & just a touch of cypress. Described by The New York Times as "uplifting, mysterious & androgynous in its appeal."
