Fir balsam spruce and pine needle essences capture the majesty and optimism of a walk through a coniferous forest after rainfall. To diffuse and create a spa-like experience remove the cork and place the reeds into the rare ESSENCE essential oil blend. You can be sure our blends contain absolutely no solvents alcohol petrochemicals or phthalates. We suggest rotating the reeds after the first hour and anytime for an extra burst of aroma.
