Fragrance Spheres™ are the perfect solution for small spaces to neutralise odours and refresh with your favourite Yankee Candle® fragrance. Spheres are activated by removal of the protective seal under the lid. As the fragrance is diffused into the air, the beads shrink. When all the beads have dissipated, it's time to replace with another jar. Perfect for small spaces like laundry rooms, cupboards, bathrooms and lockers.
