Please read the description carefully before purchasing. See the images for details. I am not familiar with the product contents, so please make your judgment based on the uploaded images and only purchase if you are satisfied. These items have been stored since my parents' sewing factory days. They used to sew Japanese clothing, and these are leftover fabrics from that time. I wasn't working at the factory then, so I don't know what the fabrics were used for. Please purchase if you can make a judgment based on the images. The composition appears to be silk, based on the burn test (it seems to have a very small amount of synthetic fiber mixed in). It has some thickness. There are wrinkles and fold marks from storage. There is a cat. Cat hair may occasionally be mixed in, so please refrain from purchasing if you are concerned.
