Enjoy an easy, long-lasting way to fragrance your car with a thoughtfully-designed diffuser that blends in with your car's interior. Simply plug it in to your car's 12v outlet to warm the fragrance refill inside, and enjoy car-filling, true-to-life fragrance for up to 60 days. The soft glow of a blue LED lets you know when the diffuser is on. Use the switch to control the fragrance strength — High, Low, or Off. Refills are mess-free and easy to change.
