Kyoto business card case made of black silk with silver lamé, gold-colored

Kinsai craft is a technique established in the Momoyama and Edo periods for applying gold leaf to cloth such as obi (sash) and kimono. This business card case is made of black silk and silver lame, and gilded with gold and silver foil. The lining is black rayon. The specifications include one gusset and one divider. The size is approximately 7 cm (length) X 11 cm (width) X 13.3 cm (length) X 8 mm (thickness) X 3.2 cm (gusset maximum) when opened. The fabric is silver lame, so it sparkles when viewed from different angles. Here is a reference video of the sliding foil processing ⇒ https://www.youtube.com/watch?v=xywm81Zz9cc&t=15s
