The Leather Wallet Case is crafted from high quality vegetable-tanned leather. The highly praised leather adds character to the case and is largely responsible for the success of the collections. It has become the signature of our collections and a hallmark for Mujjo's quality products. Manufactured with care, waxed to extend durability, and carefully treated with aniline oil to enrich the finish. Vegetable-tanned leather wears in with use and acquires a beautiful patina and polish over time.
