We handle various types of leather, including Chromexcel (brown core), saddle leather, and pull-up leather. Leather: Cowhide (Glazed Saddle Leather) All of these products use leather from Tochigi Leather. The surface leather uses the dense fibers of the bends. This leather is finished with a generous amount of oil on durable, thick, vegetable-tanned leather. The leather surface is glazed (polished for shine), giving it a beautiful luster and firm texture. Also, the coloring is done by dyeing instead of spraying paint, so you can feel the original texture of the leather along with its transparency. As you use it, it will age and transform into a wallet with a sense of weight.
