This oil diffuser is brand new. Never opened. Elegant and refined, the gypsum ceramic car diffuser uses an innovative system of diffusion through the gypsum ceramic surface of the product. A bright citrus top note is complemented with a floral bouquet. A greenery of aroma captures this appealing scent. Top note of lemon, cyclamen, citron leaf, middle notes of star jasmine, wild lily, white rose and bottom notes of bamboo, eucalyptus and dewy grass. How to use: Simply hang the diffuser anywhere that needs a scent refresh and enjoy a long-lasting, continuous fragrance release. For rapid release, hand where sunlight can hit the diffuser to supercharge the release system and intensify the strength. Please note that when doing this, the diffuser will need a refill sooner than if positioned in a cold environment. How to replenish: The gypsum ceramic diffuser is pre-scented, but you can always add more fragrance. To do so, pour an ounce of fragrance onto a standard plate. Place the diffuser in the middle of the pool. You will notice the fragrance will absorb quickly. You can repeat this process a second time to see if it will absorb excess fragrance until it hits its maximum. If the color is not even, you can brush fragrance on the front panel of the ceramic diffuser to make it a cohesive color. If the diffuser is still wet after replenishment, use a paper towel and gently pat it dry before hanging.
