I have used these sponge for over 20 years now, and they are the only sponges I use in my home. They last forever. Not to mention not a scratch on my glassware or china,yet tough enough to scrub my skillets of burnt on messes.
scrubbing fibers made from 50% natural agave plant it outlast more than regular sponges, and its made from recycled paper to save the earth and it 100% natural fibers.
