Spiced Pumpkin Smelly Jelly Smelly Jelly is the NEW Air Freshener that everyone is talking about! Since they can be refreshed over and over again, they can last indefinitely...or so I'm told! You can use them in your home, in your office, and even in your car. Now I'm not a big Pumkin fan, but I have to admit when I smelled this one, I loved it immediately! So pumpkiny and creamy, it smells so delicious, definately one of our favorite fall scents.
