This is the ZEN-GPT from the popular 900 Global "ZEN" series. Selling to organize my collection. I bought two new ones because I loved it so much, so I'm selling this one. This ball incorporates the ZEN series' first AI system. It's very easy to handle and has great pin action. I was using it actively in matches until a few days ago. If you're a thumb-less bowler, you can use it as is if the finger holes fit. Games Bowled: Approximately 100 games Weight: 14 pounds Drill: Finger holes only (two holes) Plug History: None Notes: 1. There is a cross-hatch pattern under the finger holes due to thumb-less drilling. 2. There are fine scratches on the ball surface (please check the photos). 3. Repaired (filled scratches, please check the photos). *This is a used ball. No claims and no returns. *It will be shipped in a separate box. ＜Manufacturer's Description & Ball Specs＞ This model is equipped with the first AI technology in the ZEN series.
