These little beads are actually a big deal-they neutralize odors and refresh small spaces for 45 days with your favorite fragrance. That's a month and a half of blissful use of lockers, closets, bathrooms and all those other places with stagnant air. They're so easy to use. . . just pull off the protective cover and replace the decorative lid. Clever cutouts allow the fragrance to diffuse into the air. You'll know it's time to replace the jar once all the beads shrink. Ingenious!
