This is a cover for the erhu strings. It's handmade, so there may be some slight imperfections like warping or puckering, and it's not perfect, but I made it with care. Approximately 20cm x 54cm. It has three plastic snaps. The outer fabric is Chinese jacquard. It's a very beautiful and cute fabric. It also has a lining. If you understand that this is handmade, thank you very much. ^ ^
