Directions: Place 5-10 drops of oil in the hole. Tilt the diffuser to spread the oil. Suggested Uses: Hang in a sunny window. The sunlight will warm the oil, intensifying the aroma. Hang in a closet or use as a drawer sachet. Add a self-adhesive velcro strip to the back of the diffusers, and use it as a car atomizer or to decorate a wreath. Product Notes: Our terra cotta diffusers give users a wonderful way to enjoy the benefits of aromatherapy. The porous surface gently disperses the essence of the oil into the environment. Since they don t require heat, these diffusers are ideal for absolutes and citrus oils, some of which are chemically altered by heat.
