Coffee and charcoal (along with other natural ingredients) are packed into the handcrafted cotton bags which absorb and neutralize unwanted odors. There are no chemicals or fragrance added. It’s compact and discreet, and works best in small areas. And because Steve made the bag with pets in mind, he added bitter apple to keep animals from chewing on it. Hang one inside a closet, slide it behind the trash can, stash it in the car, or place it in any spot where things might smell not so fresh. A bag should last around three months, and you can shake and roll it to reactivate its natural funk-fighting power.
