I wore one on my arm for a dance recital. It's elastic and seems like it could be used for anything. I think it would be cute to wear around your neck or put in the pocket of your jeans. I think it could also be used for hair. The material is rayon-based, which is wrinkle-resistant, not cotton. If anyone wants to buy one individually, they are 300 yen each. Please send me a message if you'd like me to create a dedicated page for you.
