Reed Diffusers provide a flameless air freshener and make an equally effective centerpiece. A deceptively simple and elegant grouping of bamboo sticks - is both attractive and unusually effective. The reed diffuser oil travels up through the bamboo sticks and fills the room. Reed diffusers are inviting and offer each space its own unique fragrance. Our reed diffusers come in five different scents Gourmet Vanilla Sandalwood Mandarin Grapefruit Tropical Berry and Gardenia. Includes twelve reed diffuser sticks and is available in either the 4.0 oz or 8.0 oz. The 4.0 oz reed diffuser lasts up to 3 months and the 8.0 oz up to 6 months.
