This is a silk (正絹) accordion card case. The outer fabric uses repurposed fabric from a komon kimono, and the lining is black cotton. It can hold 17 cards, and 34 cards if you put two in each slot. Interfacing is applied to the outer fabric, and Velcro is used for the closure. It is carefully made, but as it is a handmade item by an amateur, there may be some imperfections such as distortion or wrinkles. Thank you for your understanding.
