Vent stick air fresheners can be clipped discretely into car's air vents using air flow from vents to release scent and eliminate odors. Their small size allows for combining fragrances, or adjusting the level of fragrance by choosing the number of sticks used at one time. Longer lasting alternative to hanging cardboard and aerosol air fresheners for cars. Can also be used in the home, office, gym bag, luggage. Ideal for smaller vehicles or anywhere a fresh, light scent is desired.
