*Sourced and Made in the U.S.A. The wool in our MC-1™ Batts are from sheep raised on U.S. Farms, supporting the American farmer. BIO-PROCESSED: This Living Felt wool was processed and washed using a bio-degradable Eco-Friendly GREEN soap and green process. NO harsh chemicals are used, and the wool is not carbonized. Small amounts of vegetable matter in the wool is common and to be expected.
