Please read to the end. This is a personalized product that was customized by Mr. Murai, a racket meister in Chiba. You can find Mr. Murai's YouTube channel, which features videos for players and Raffino, for your reference. The customization includes reshaping the grip from size 4 to 2, and specifying a Wilson end cap, the slightly angular type from the Pro Staff 97 v11. Silicone was added inside the end cap for balance adjustment. The balance and feel were set for easy swing-through and good ball flight. The buyer will receive the customization details and the original data sheet. However, my personal information will be removed. A new v13 grommet set will be included. Please check the photos for touch-up repairs and scratches. I was using this racket until recently, and the strings were replaced on November 21st. The strings are: vertical - Baiface 130 at 48p, horizontal - Alu Power Rough 125 at 45p, with three patches, 10 Elasto Crosses, almost the same setup as Federer's. However, because the strings are different from the original setup, the current specs are 333.6g, 316mm balance, and SW 312.5. This is a matching pair with item A, which I listed earlier. I will also accept combined purchase requests. I would like to ask that those who understand that this is a used item purchase it. Please understand that I will not accept returns or exchanges. I will ship the racket in a cardboard box suitable for rackets. Thank you for your understanding. Thank you for viewing.
