This slim bifold card holder features pockets on both sides, holding around 15 business cards or 5 standard cards. A built-in spacer allows for smooth access. The veg-tan leather develops a deep, rich patina over time, enhanced by the natural oils from your hands. The kakishibu (persimmon tannin)-dyed version, known as the "dye of the sun," gains even more depth with use, offering insect repellent, anti-fungal, and water-resistant properties.
