Utterly modern in monochromatic black. Our reed diffuser infuses the air with the invigorating scents of cypress, eucalyptus and thyme grounded by the richness of rose, myrrh and sandalwood. The diffuser's black reeds absorb the oil and release the aroma gradually for the ideal level of scent. To refresh the fragrance, simply jostle the reeds, or take them out and put them back in upside down. Packaged in a black gift box, the matte black glass vessel has a bold look that adds a touch of drama to your coffee table, dresser or mantel. Part of our Monochrome scent collection, the No. 02 Onyx diffuser is a Crate & Barrel exclusive.
