The Library Luxury Reed Diffuser RefillEvoking mahogany shelves full of leather bound books and reading under the flicker of warming candlelight. Your ceramic diffuser is made to be kept. When the fragrance fades, simply replace the oil and reeds and The Library comes back to life. The same rich blend of pomegranate, pink pepper, jasmine, amber and cedarwood. Or try a different fragrance in the vessel you already love.
