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 dont require heat, these diffusers are ideal for absolutes and citrus oils, some of which are chemically altered by heat.
