Leather floor and wall tiles are made from vegetable-tanned cowhide. The floor and wall tiles are made from the same material used to manufacture shoe soles. Vegetable tannage, which uses tree bark as the tanning agent, creates a very durable and versatile product. After tanning the tiles are dyed with a combination of aniline dye and wax solution, which is driven into the tile under pressure to create a beautiful finish. Tiles are 100% full natural grain leather.
