Hermann Oak Leather Co., founded in 1881 in Missouri, USA, is a leading American tannery 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, there may be some scratches and stains, which are characteristic of natural leather. Please understand that these will become part of the texture as you use the product.
