Thank you for viewing. Based on the concept of "durable, long-lasting craftsmanship," these are handmade items carefully hand-stitched one stitch at a time, without using a sewing machine. ■ Craftsmanship Details Luxurious use of Japan's highest quality "Tochigi Leather." Genuine Tochigi Leather purchased from authorized retailers is used for all parts. The main body uses approximately 2mm thick leather, providing a substantial feel when held and allowing for long-term use without worrying about deformation. The meticulous "hand-stitched" finish is more resistant to fraying than machine stitching, resulting in a durable construction. You can feel the "one-of-a-kind" texture unique to handcraftsmanship. Smooth Operability Reliable YKK zippers are used. We have also focused on the smoothness of opening and closing. ■ Product Specifications Product Name: 4-Key Case Material: Cowhide (Tochigi Leather) Size: 10cm (H) x 6cm (W) x 2cm (D) Shape: Type C Colors Body: Natural Zipper: Navy Stitching (Thread): Camel ■ Characteristics of Leather Products and Requests Due to the use of genuine leather, there are individual differences inherent to the leather (color unevenness, scratches, differences in texture). We hope you will enjoy the unique expression as a "testament to the life of the cow," making it one of a kind in the world. *Regarding the aging process unique to vegetable-tanned leather (aging), If you search for "Tochigi Leather Aging" in image search, you can easily imagine the wonderful color changes after use. ■ About Shipping Since it is not something that breaks easily, it will be shipped in an envelope with a storage bag. Due to being a handmade item, we ask for your understanding. Color...Navy系 (Navy-based)
