What it is: A first-of-its-kind innovation, NEST Fragrances Liquidless Diffuser is a maintenance-free product that disperses your favorite scent into the air for 90 days without the use of a flame or liquid, with a scent strength that can be customized using the included patent-pending biodegradable and compostable ScentSticksTM made from sustainable paper infused with the brand's fragrance oils. The open-air vessel (sold separately) creates an optimal fragrance diffusion while adding an elegant touch to your decor.Fragrance story: Bamboo features notes of flowering bamboo mingled with a variety of white florals, sparkling citrus and fresh green accords. How to use: Place the vessel on a sturdy surface away from vents and windows. Add ScentSticks to the vessel. You can customize the number of sticks based on the size of your room and preferences. NEST Fragrances recommends using two for smaller rooms or a subtle scent, three for mid-size rooms or a moderate scent and four for large rooms or a more intense scent. Refresh the fragrance every 30 days by adding another ScentStick to the vessel. To ensure your ScentSticks stay fresh, leave the unused sticks in the provided airtight, resealable bag and store in a cool, dry place. To clean the vessel, wipe down with a damp cloth. Includes five ScentSticks; vessel sold separately Made in the USA
