Nubuck is a top grain polished leather. Softer and smoother than suede, which is the back side of the leather. We source our nubuck leathers from France, Germany and the United States. Nubuck is meant to pick up natural oils over time from hands and the environment. This adds to the character and patina and helps build up its own resistance to stains. We still recommend some basic care. Avoid contact with heavy oils and wax. Be cautious wearing against denim as some denim dyes can rub off on leathers.Mineral Earth has a soft and drapey mottled tone and a luminous, subtle shimmer. This swatch is 2"x 2" for previewing or crafting. Swatches are final sale.
