Model: SG1139 Product Details: This semi-hard case combines artificial suede and vegetable-tanned leather. Ultrasuede, developed by Toray Industries, Inc., is a recycled material that boasts excellent durability and high maintainability, making it easy to care for. While genuine suede offers a luxurious look and feel, it can be prone to color transfer and has durability issues. Ultrasuede solves these problems, and is used for the exterior of this case. Unlike genuine suede, its greatest feature is that it can be used daily without worrying about damaging it. The interior is lined with vegetable-tanned leather that allows you to enjoy the aging process. This vegetable-tanned leather has a moderate firmness, but with repeated use it softens and gradually changes to an amber color. The appearance varies depending on the color, with some colors looking just like genuine suede and others being colors rarely seen in leather. This product uses dyed genuine leather. If rubbed against clothing while damp, color transfer may occur. Please be especially careful on rainy days or when wearing light-colored clothing. As it is natural leather, there will be individual differences in appearance.
