There are scratches and dirt from normal use, but it's still in good working condition. Thank you. This racket uses the Micro System, a string pattern that PROKENNEX previously focused on. The Black Ace Micro is the top-of-the-line model. Face Size: 95 Pattern: Main 22, Cross 30 Length: 27 Frame Thickness: 18mm Grip: 2
