These scented aroma sachets make great car fresheners, or any small space that could use a little fragrance booster: drawers, luggage, lockers, or your son's gym shoes ;-) Aroma beads are small polymer beads which can hold about 30% of their weight in fragrance. Our aroma beads are in an organza bag and are ready to be placed in the location of your choice. The scent will last 8-12 weeks, depending on usage.
