The Leather Sleeve 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 the leather collections and a hallmark for Mujjo’s quality products. Manufactured with care, waxed to extend durability, and carefully treated with aniline oil to enrich color tones. Vegetable-tanned leather wears in with use and acquires a beautiful patina and polish over time.
