This custom car air freshener has a good cause to match its good scent. The iconic tree-shaped air freshener was distributed in Romanian gas stations to raise awareness about the surge of drunk driving that occurs around Christmas time. This is a perfect place to imprint a warning against drunk driving – drivers can’t help but see (and smell) it every time they get into their cars. This provides a much better image of awareness than an awareness bracelet. The dent in the tree is a nice touch also!
