This is a very rare model, not available in Japan. It's a Wilson Pro Staff Six One 100 V13 G3, which was sold overseas, exclusively at tennis points in the UK. It's out of stock. Although the mold is the same as the Six One 100 V14 from Japan's Pro Lab, I personally think the black base with the classic Pro Staff yellow and red lines looks very cool. Replacement grommets are included. I purchased it for approximately 38,000 yen, including shipping and customs fees. Original Specs at Purchase: 305g, 310mm balance, SW278, 16x19 pattern, 100 sq. in. head, 22.5mm beam, SW was low, and the racket didn't provide much power, so I customized it to make it usable in matches → Customized Specs (including strings and overgrip): 334g, 326mm balance, SW332 Lead tape is applied with black paint. 2g total on both sides at 11 and 1 o'clock, and 6g total on both sides at 10 and 2 o'clock. String weight is 16g. The strings are Bi-Phase 130 at 52 lbs (vertical) and Blast 125 at 49 lbs (horizontal), and I've added elastocross at the same position as Federer to prevent notching. The overgrip is 5g. This resulted in the above custom specs. If you are an intermediate to advanced player, you should be able to hit the ball easily with power, and the ball will travel like a pro's. The customization is close to the Tennis Topia specs. If you don't want the lead tape, please remove it yourself after purchase. I think it will return to the quality of the commercially available product and won't provide much power. It has been used only once, so there are no noticeable scratches, but please check the photos and purchase if you understand that it is a used item. It will be shipped in a racket-specific cardboard box. I will not respond to purchases made through a separate account after a comment to prevent any trouble. No returns or refunds. Thank you very much. Thank you for looking.
