Hermann Oak Leather Co., founded in 1881 in Missouri, USA, is one of America's leading long-established tanneries with over 120 years of history. The carefully tanned natural vegetable-tanned leather is characterized by its firm thickness and supple feel. The generous addition of fat gives it a moist, natural luster and a wild texture, making it a leather that offers an exquisite aging process. Notes * Each item is handmade, so there may be individual differences. Also, because natural leather is used, some scratches and stains are characteristic of natural leather and will become part of the texture as you use it. We appreciate your understanding.
