The main body material is made by the only tanner in Japan that has acquired *LWG (Leather Working Group) certification, and the steer leather is chrome tanned and dyed, and a special treatment is applied to rub the silver surface to prevent it from lifting. Tight coat processing is performed using chemicals. Smooth the silver surface with a binder and spray the paint to create beautifully colored leather. The surface is embossed with a kip-like pattern to create a smooth texture. The accessory leather used for the interior is Kip leather, which has a good balance of texture and durability. It has a high fiber density, is supple and has a good taste, and is said to be ideal for making leather accessories. The surface is made of resin to prevent scratches, and the leather has a deep luster. All models have a specification that allows you to insert an IC card in the front. *LWG (Leather Working Group) is an international organization that audits tanneries. In addition to evaluating and ranking environmental compliance and ability, we pursue traceability of leather.
