Who wants to ride around in a vehicle that smells like old gym socks, stale French fries and spilled Diet Coke? No one, that’s who! But instead of going and buying your run-of-the-mill pine tree-shaped air freshener to hang from your rear view mirror why not create your own custom car air freshener on Zazzle! Fill your car with one of our five unique scents like Emerald Sea or Island Breeze and keep your olfactory senses revved up. Our custom car air fresheners come in a number of different shapes as well, such as heart, rectangle and square. No more pine tree for you! Add your own image, design or photo to make it even more unique.
