Directions for Use: Once opened unscrew the lid and remove the clear stopper. Discard the clear stopper, this is used to transport the diffuser to avoid leakage. Tilt slightly to saturate the cork for a strong smelling car perfume.If you feel your diffuser needs a little boost gentle shake the bottle to soak the cork for a stronger scent throw. Please note where possible do not leave in direct sunlight, this will make the fragrance oil evaporate quicker. PLEASE NOTE: Do not place diffusers directly onto polished, painted or leather surfaces as accidental spillage can cause damage to surfaces.
