【Invisible Crown Wire】: An invisible wire allows the extension to lie smooth and flat on the head, making it comfortable and secure.
【Adjustable Wire】：If the size doesn't fit you, adjust it by tightening or loosening the wire. Get beauty and confidence in seconds, instant new look and no one will find your secret.
