15-Pack Black Glass Hanging Car Diffusers

This 15-piece set of black glass hanging car air freshener bottles is designed for refillable fragrance use with a sleek, dark appearance. Each bottle is empty and intended to be filled with perfume, essential oil, or air freshener liquid. The black glass gives the bottles a modern, understated look that can complement a range of car interiors. The bottles can hang from a rearview mirror or other suitable location using the included string, and they can also be placed in a bathroom, bedroom, kitchen, office, or living room. To use, open the cap, add fragrance, turn the bottle upside down for a few seconds so the oil soaks through the stopper cap, and hang the bottle in the desired spot. The fragrance is then released gradually through the hole in the stopper. The compact size makes the bottles portable and easy to store. Because the bottles are empty, essential oils and perfume are not included. This set is suitable for people who want a larger supply of refillable hanging diffusers with a simple, dark-colored design, and it can also be shared as a small gift.
