Grip size...3. The black grip is size 2, but it has been adjusted to 3. Head size (square inches)...95-99.9 sq. inches Gender...Boys Weight (g)...305 - 319.9g The blue grip is a new, stored item and has only been used a dozen or so times. Compared to the Pro Staff, the rounded frame structure, which has softened corners, creates flex and a holding feel, making it easier to handle and a Pro Staff designed for Japanese players. It's a 1-inch long type, so it's good for increasing serve power and speed, and also for those who use a two-handed backhand. With a black, red, and gold frame, it's a color scheme not seen recently, so I often got noticed when using it.
