Here are the details: Euro Cloth #20: With the absorbency of a paper towel and the reusability of a sponge, the Euro Cloth #20 is a modern and eco-friendly solution for wiping even the messiest of spills. Made from sustainable pine trees, the Euro Cloth is long lasting (one Euro Cloth equals 17 rolls of paper towels), anti-bacterial, dishwasher safe and biodegradable (the Euro Cloth disappears after 7 weeks if buried in the soil). TWIST products are all natural; the cellulose used to make TWIST products is sourced from renewable tree farms. In addition, TWIST takes special care to make sure 99/97% of all waste is reused in production, and is committed to continually improving production process to minimize the effect on the environment. The suggested retail for a 3-pack of Euro Cloths is $3.99. They are on sale at our Whole Foods right now for $2.69, so we've stocked up.
