Thank you for viewing. The fabric on the front is silk, but the lining is unknown. It's a gold color, so it might bring good luck with money?? I noticed it for the first time when I took the photos. ★Size: 20 x 14 (cm) Please understand that measurements and photography are done by an amateur. I will pack it carefully, but I will send it compactly. I always try to ensure a smooth transaction. Also, I do not accept returns, so thank you for your understanding. As I am an amateur, I would like to decline purchases from those seeking perfection.
