Ritz Clean Toss-N-Soft Dryer Balls blue. These Ritz Clean Toss-N-Soft Dryer Balls are safe for home and family. The fabric softening ball is ideal for the dryer to reduce drying time and can be used again and again. They work in the dryer to soften, separate and fluff fabrics. As your clothes tumble, so do Toss-N-Soft Balls, bouncing off the walls of the dryer, off the clothing, separating them, and allowing air to flow through them more efficiently. The added efficiency dries clothes faster, and makes fabrics fluffier than other methods further aiding in the softening process. Each ball is 2 1/2 inches in diameter.
