Odor Eliminating Scented Beads stick to odor molecules, neutralizing them on contact. Keeps odors out and good air in. Our smelly jelly room air fresheners are handmade to order in the fragrance (s) of your choice. These 12 oz air fresheners last approximately three months and are a fabulous flameless scenting option- perfect for cars, offices, dorms, bathrooms, and more! My favorite place to use them is in the car (they fit perfectly in the cup holder), the bathroom on the back of the toilet tank, on the nightstands in the bedrooms, and at the office. Choose your scents from my fragrance listed.
