This is the model Yuka Saso used at the U.S. Open. Apparently, she attached this to a putter that was about an inch longer than usual and gripped it shorter for putting. I tried it too, but it didn't suit me, so I removed it immediately. It's in good condition, but it has been used once, so please be aware of that. I'm selling it at a low price, so please give it a try.
