Genuine silk, custom-ordered Oshima Komon, 100% silk remnants. Antique item. I measured the size with a measuring tape because it's difficult to rewind. It looks like something from Chikusen. If you are concerned about the color, please comment. I will take photos at a different time. I am an amateur, so I may not be able to answer detailed questions, but please comment if you have any questions. Please purchase only if you understand that this is a personal storage item.
