Thank you for viewing. This item uses soft and smooth, high-quality lambskin, and is a step above the rest, allowing you to subtly portray a businessman in business settings. This lambskin is a luxurious item using Ethiopian lambskin, which is said to be the pinnacle of leather. The dramatic temperature differences in the growing environment create thick fibers with excellent elasticity, making it a material with superior characteristics compared to general leather. The simple and refined design works well in both formal and casual settings. There is one card pocket on each side inside. There is also one card pocket on the back. The main storage area inside is large and can hold up to about 50 cards, but about 30 cards is a reasonable capacity for the flap to close neatly. - Color: Black (BLACK) - Material: Lambskin (lambskin/genuine leather) - Type: Flap-style business card holder - Number of pockets: Main storage x 1, card pockets x 3 - Size: 7cm height, 11cm width, 2cm depth - Accessories: Outer bag Shipping will be via Click Post. There is a tracking number, but since it is a postal delivery, there is no compensation, so please understand. Note: Due to the natural material, there may be wrinkles, creases, and blood vessels, but this is the natural texture of the leather and is not a defect. Please understand. The last two images show the same product in four colors, and are images for comparing the color differences. From the left, the colors are black, navy, dark green, and dark brown.
