This is a business card holder made with Italian leather and Mommi pigskin. The reference images feature Lugato shoulder and Maya (waxed) leather. In addition to these leathers, we can accommodate your requests. The hook is made of brass. You can choose from brass or nickel colors. *The Maya version does not have a hook. You can choose whether or not to have a hook, as well as the leather. The business card holder can hold about 10 standard-sized business cards on one side, making it convenient when you want to carry a few. By shortening the stitching width on one side, you can smoothly insert and remove business cards. The hook prevents the business cards from falling out. It's sized to fit easily in a chest pocket. It is finished with a single piece of leather, and the edges are treated all the way around and dyed with a black matte paint for a calm impression. Please feel free to contact us for orders or any other inquiries. *Please understand that the number of days until shipment is approximate, as we will create the product after receiving your order. It may vary depending on the order details. *Please understand that minor scratches and scuffs are part of the natural expression of the leather. *Prices are for reference only. They vary depending on the materials and specifications.
