This is a simple ID card holder made of genuine leather. The materials used are Tochigi leather (dark brown) and light camel-colored nubuck leather in a bi-color design. The stitching is done in a matching color. The front card slot is grooved to perfectly fit JIS standard cards, preventing them from shifting. It's the size of a standard ID or Suica card. A transparent polyolefin sheet is sewn onto the surface. The strap holder uses a spring hook, allowing you to remove the ID card, etc., by detaching the holder part. There is a card pocket on the back. *Please note that this is a handmade item. There may be minor scratches or uneven stitching from the manufacturing process. *The sample card (white) is not included. *The color may slightly differ between the photo and the actual product depending on your monitor. *Since natural leather is used, there may be slight wrinkles or stains.
