Well here you have it! One of the best scented diffusers ever. These Fragrance Beads are small plastic beads, that absorb fragrance oils. They are PERFECT to use as a car air freshener. Place the organza sachet over the air vents, and your car will smell wonderful! The Fragrance Beads last at least 3-6 months if not more, and can be refreshed with more fragrance oil (available separately). Each sachet holds 1 ounce of fragrance beads. Our Fragrance Beads Sachets can also be placed in a drawer, locker, closet and shoes and anywhere else needed. The beads are their strongest, when air is flowing through them. You will not be disappointed when you purchase these little guys!
