These small clear plastic poly beads, known as Aroma Beads, can absorb up to 30% of their weight in the fragrance oil, providing a long-lasting scent that can last up to six months. They are a great alternative to candles and can be placed in a decorative container such as a glass vase or potpourri dish. Additionally, these beads can be used to create car air fresheners by cooking them in a cookie cutter. Mixing different colors of beads can create a beautiful design.  Our "wider spec" aroma beads are slightly more variable than our premium aroma beads, but they still make a great freshie and/or sachet. The shape, size, clarity, absorption rates, and cooking temps may vary slightly from lot to lot.
