We use natural, low environmental impact, rattan reeds over synthetic fiber reeds. Rattan is less likely to become over saturated or clogged, which allows oil to diffuse at a much slower pace. We suggest flipping the reeds after 30 minutes and thereafter every 1-2 weeks to ensure maximum fragrance diffusion. Perfect for small spaces and high traffic or drafty areas. Diffuser lasts approximately 6 months. Includes fifteen 10" rattan reeds. Store away from direct sunlight, flame and children. Liquid color will vary based on fragrance oil. Bottle measures 2.7" x 5.3" h 7 fl oz (207 ml) INGREDIENTS: Vegan renewable coconut oil infused base, phthalate & paraben free base and fragrance oils.
