Refresh your favorite Greenleaf fragrances with our Diffuser Oil. Use it to top off your Greenleaf Flower Diffuser (refills it one additional time) and your Greenleaf Reed Diffuser (refills it two additional times). Carefully pour into your existing vessel to keep the scent you love going! Gingerbread is a warm, nostalgic fragrance — fresh ginger and warm cinnamon with a sweet vanilla finish that smells like it just came out of the oven.
