Thank you for viewing! This is DONIC BlueGrip J12 black 2.0, produced by Zhang Jike. I used it for just under two months on a Fan Zhendong ALC blade. (Practicing 2-3 hours twice a week + one match) It has shrunk a little, and the bounce has decreased slightly, but I think it still generates a lot of spin. The current size is about 155 x 149. It's in reasonably good condition, but please understand that it's been inspected and stored by an amateur. Also, to prevent any problems, we will not accept returns or exchanges after purchase, so please check the condition carefully in the photos before purchasing. Bulk purchase requests are welcome! Shipping will be via simple methods like Nekopos.
