Our product is dual purpose. It is a car charm and air freshener all in one! So how does it work? The freshies come unscented, however we include a 3 mL bottle of fragrance for each freshie- or we can hold off on the fragrances if that is more your vibe. Once the bottle of fragrance is used, then the freshies can be re-scented with your favorite room spray, perfume, essential oils, etc. Each air freshener comes with cord that you can tie yourself to get your air freshener in the perfect spot while hanging from your rearview mirror. Freshies are sent in clear cello bags with branded bag toppers or backing cards. Scents sent at random. Please message us if you have any questions.
