It’s like walking into a still, quiet library. It’s like picking up your favorite, old, worn book & opening it up & taking a deep, steadying breath. It’s comforting. It’s grounding. It’s a smell you didn’t even know you missed. A complex blend of many essential oils but the two main stars are Cedarwood & Vanilla. Follow your essential oil diffuser instructions.
