This is a silk accordion card case. The outer fabric is Oshima Tsumugi dyed, and the fabric uses unused cloth left over from cutting kimonos. The lining uses black cotton. It holds 17 cards, and 34 cards if you put two in each slot. Interfacing is applied to the outer fabric, and Velcro is attached to the opening and closing part. It is carefully made, but it is a handmade item by an amateur, so there may be distortions and wrinkles. Thank you for your understanding.
