Love the scent of Gain Detergent, but wish you could somehow add even more of that great scent? When you meet what we’ve got for you, you’ll feel... fireworks. They’re scent beads that give your clothes an extra boost of scent. The more scent beads you add, the more amazing your laundry smells. Just shake the scent beads directly into the drum of your washer before your clothes. You’ll get 12 weeks of freshness when you store your clothes.
