A Sophisticated Woody Fragrance with Oakmoss Depth. White Birch and Oakmoss Fragrance Oil is a refined woody fragrance built around the distinctive scent of birchwood, softened with earthy oakmoss and warm aromatic depth. Notes of precious spices and smoky resins add richness and character, while a smooth leathery undertone gives the scent a confident, contemporary finish. Grounded, balanced and atmospheric, this fragrance creates a polished woodland-inspired aroma when used in a compatible waterless electric scent diffuser.
