Genuine silk. This is a stylish obiage (decorative sash) made of flowing, genuine silk with an overall cherry blossom pattern and a chic gray gradation. The obijime (sash cord) is also unused. It's a flat weave in a gray and blue-gray color that isn't too dark. There are some fold creases from storage. If you are sensitive to this or concerned about minor details, please purchase directly from a specialty store. No price reduction is possible.
