As effective a centerpiece as it is an air freshener, the Alora Ambiance diffuser truly is a one-of-a-kind product and makes a perfect gift. Its exquisite design and attention to detail attest to its Italian origins while its wicking device - a deceptively simple and elegant grouping of sticks - is both attractive and unusually effective. The liquid travels up through the sticks and fills the room. It is inviting and offers each space its own signature fragrance.
