Revolutionize your cleaning routine with Frog Clean Smart Double Action Cellulose Sponges. With a heavy duty scour sponge on one side for tough stains and a cellulose sponge made from natural pulp on the other for gentle dishwashing, these sponges are the perfect all-in-one solution. Use the heavy duty scour sponge end (red) for stubborn marks and stains that require a stronger scrub (due to its scrubbing power, it's not recommended for items that can be easily scratched). Use the cellulose sponge end (yellow) for a scratch-free wash and rinse, even with your most delicate dishes. The scour material (nylon, non-woven fabric, abrasive stone, synthetic resin) is made in Italy, and the cellulose sponge material (derived from natural pulp) is made in France, and it is then meticulously produced/packaged in Korea, so you can rest assured you are getting the highest quality sponges. Comes in a convenient 2-pack. Each sponge = Approx 4.3 x 3 inches (Approx 0.75 inches thick)
