Not yet available in Japan. 100% silk, reportedly (personal opinion) leaves no marks, doesn't tangle, and reduces damage. A scrunchie set from a brand loved by celebrities like Taylor Swift and Hailey Bieber. Purchased as a set at Nordstrom in Hawaii, so the package has been opened, but the items are unused and new. I've actually used a different color and it holds long hair securely. I was worried it would slip off since it's silk, but it was fine even during a flight and travel of over 12 hours. Two beige scrunchies.
