Thank you for viewing! I made a card case featuring a Shiba Inu. As shown in the example image, you can use it with commercially available cards. Size: 12.5 x 17 cm when laid flat Interfacing used Card case included Since there's no fastener, you might need to secure it with a rubber band... This is a handmade item by an amateur. There may be some imperfections. Thank you for your understanding.
