The pattern of the South American bull skin is all natural. The precious pieces come from the giant grasslands of Brazil and Argentina, can reach dimensions of 4 to 4.5 sq. m. and are renowned for their premium tanning. The brand marks are still detectable in part as distinctive proof of authenticity. Since this is a genuine, high-quality natural product the basic color and patterns may vary. A rug made of bull skin may show natural features from brands, insect bites, injuries and other influences. The fur will also vary in length, which is why these rugs are so authentic and unique. The bull skins are very easy to clean: Simply vacuum, use a rug beater or a moist cloth to wipe off stains.
