This is a non-woven fabric bag that came with a Yonex racket when I bought it. It's new, but I only used it to carry the racket from the store to my home. There are some wrinkles because a rubber band was put around the grip of the racket. It's a very sturdy non-woven fabric. For those who cherish their rackets, how about it? Please purchase this item if you understand that it is a used item.
