I've crafted a business card holder from a single book. This business card holder evokes the appearance of an old Western book with a spine, expressed through layers of leather (stacked leather). The sides feature the appearance of a "book cross-section" created by the layered leather. It has a quiet presence when held in your hand. The exterior is made of calm brown genuine leather, and the interior has a simple design with minimal decoration to avoid hindering the insertion and removal of business cards. All pieces are hand-cut and hand-stitched. Please enjoy the unique individual differences and textures inherent to leather, which are not found in mass-produced items, as part of the work. Specifications ・Number of business cards that can be stored: Approximately 20 ・Size: 12 x 8 x 1.5 cm ・Inner dimensions: 9.5 x 6 x 1 cm ・Material: Genuine leather ・Construction: Hand-stitched ・Color: Brown This is a business card holder for adults that naturally blends into a study or desk.
