This is a Yonex Duora 7. I've had it for about six months, and it has a crack-like scratch (see photo 4). I haven't strung it since this happened, so I can't guarantee that it can be strung properly. There are also some peeling spots (see photos 5, 6, and 7). The original grip has been removed. I think it's best if you purchase it with the idea of repairing it before use. Please purchase only if you understand the above.
