This set of two empty hanging car air freshener bottles is designed for people who prefer to choose and change their own fragrance. Each bottle is made of glass and measures approximately 3.5 cm, making it a compact pendant that can hang from a rearview mirror, window sill, or other suitable spot. The bottles are empty and do not include perfume or essential oil, so you can fill them with the scent of your choice. The simple transparent design allows you to see the liquid level and refill when needed. A hanging cord is included for easy installation, and the small size is intended to add a decorative touch without taking up much space. The bottles can also be used in bedrooms, offices, bathrooms, closets, or other small areas where a subtle fragrance is desired. Because the product is made of glass, it should be handled carefully and hung securely to avoid breakage. This set is a practical option for anyone who enjoys customizable car fragrances and simple, reusable hanging decorations.
