Balsam Fir, Birch, Cedarwood. Spruce brings the outdoors in with its fresh, forest-inspired blend of Balsam Fir, Birch, and Cedarwood. A calming woodland scent, reminiscent of pine needles crunching, cozy log cabins, and the festive holiday scent of a Christmas tree. Perfect for flameless, 24-hour home-scenting, our Reed Diffuser comes in a beautiful amber glass bottle with five natural fibre reeds. Flip the reeds every few weeks to refresh the fragrance.
