A card holder made of a single piece of leather folded in and secured with rubber. The simple construction eliminates waste, and the texture of the leather stands out. The card can be removed by lifting the flap sandwiched between rubber bands, making it easy to exchange business cards. The logo that you see when you open it is also casual and nice. The leather is vegetable tanned leather with a smooth texture. As you use it, it becomes glossier and becomes more and more flavorful. Please enjoy watching the leather change over time.
