Pure silk. Feels very nice on the skin. Slight stains. Made from the lining of a kimono. It's a bag. Extra long size. I think it would be good as a pillowcase too. If you don't need the elastic, please comment. 48 x 78 cm 50 cm elastic will be inserted. Please give it a try! Silk is very good for your hair. I've been using it for a long time too. Please refrain from complaints. There may be wrinkles, holes from unraveling, and stains. Because it is a remake of an old kimono, there may be odors. Also, please refrain from purchasing if you have a different image or are nervous, as well as those who give bad reviews. Because it was made by unraveling and washing an old kimono, there may be stains, thread marks, scratches, and scorch wrinkles. We appreciate your understanding of amateur remakes from old fabrics. I am a beginner at handmade items. There are distortions, and I am not very good, but I would be happy if someone could use it. Remake items, we will offer combined shipping discounts. We are waiting for your requests.
