These smelly jars are the best car air freshener I've ever used. I love that it isn't too strong yet lasts for months. Mine seem to last for around 4-5 months and that was even though hot summer's in Phoenix. The coconut mahogany is by far my favorite.
I wished I would have found them sooner! When my cup sweats in the car it gets absorbed by the coaster. (Or if someone "dumps" their soda--no more sticky mess, just pull out the coaster and clean it.) I loved them so much that I have already purchased them to use as stocking stuffers!! Thanks Smelly Car Jars!
