Small Scent Bag - Non-Stock Scents

What are the only senses that haunted houses do not attack? Taste and Smell !!! We are here to help you with one of those. Imagine walking into a forest where you actually smell evergreen and pine trees. You wander through the forest and see a fallen tree; as you approach it smells like rotten wood, every step you take the smell of the decaying leaves rises from the ground. What about the smell of a freshly dug grave in your cemetery? ...or the scent of a circus with freshly popped popcorn and the sweet smell of cotton candy?
