You can adjust the strength of the fragrance by sliding the case up or down, which widens or narrows the opening through which the scent is released. Comes in a compact design that adheres to the air vents and will not get in your way while driving or moving in the car. Lasts around 45 days, and comes in a sweet floral bouquet scent.
