A nightcap that can be worn during a good night's sleep to prevent friction, static electricity, and sleeping habits and reduce hair damage. If you are worried about long hair getting tangled when you sleep, you can quickly and easily take care of it with this hair creperie. The side that touches the hair is 50% silk and 50% cotton. The outer material is 100% cotton. Since it is a natural material, it can be worn comfortably all year round. Not only as a nightcap, but also as a substitute for a hair band during the day or as a hygiene hat in the kitchen. I finally found it. A nightcap that makes you want to show it to people. <MATERIAL>COTTON, SILK made in china photos taken at the " L Y U R O Tokyo Kiyosumi".
