Up for sell is a new babolat pure drive play. The grip size is 4 1/4. I had taken it out of the original wrapping and strung the racquet but never got around to using it. I rewrapped the grip in plastic wrap so the grip wouldn't get dirty. I have no idea if the play function works or not. I was never able to get it to turn on. Maybe you will have better luck with it. If you have any questions feel free to ask. Enjoy!!
