Pure silk. It feels very soft against the skin. Made from the lining of a kimono. It's a bag. 44 x 63 cm Insert 50 cm of elastic. 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 making claims. 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 than expected, or if you are a perfectionist. Because it was made by unraveling and washing an old kimono, there may be stains, thread marks, abrasions, and sun-induced wrinkles. We appreciate your understanding of these amateur remakes from old fabrics. I am a beginner at handmade items. There may be distortions, and I am not very skilled, but I would be happy if someone could use them. Remake items, we offer combined shipping discounts. We are waiting for your requests.
