Aroma Beads are small translucent plastic beads that absorb up to 40%* of their weight in fragrance oil. The fragrance can last up to six months, depending on the conditions it is used in. They are perfect for use in potpourri, sachets for cars, closets, drawers, luggage, etc. and as an alternative to candles. The aroma beads look radiant in organza baggies or in pretty glass jars, or even as dry potpourri.
