Place scent diffuser vase on a stable surface that is not wood, lacquered, polished, or painted. Pour diffuser refill oil into the diffuser vase. Slender rattan reeds absorb the scented oil releasing a fresh, serene ambiance. Simply flip oil diffuser sticks to renew the fragrance. Control fragrance intensity by number of reeds used in the fragrance oil and frequency of flipping the reeds.
