ONOFF wedges, 51 degrees. Purchased new in December 2024. I also have the 58-degree and 64-degree models from the same series, which I use frequently, but I haven't used the 51-degree much, so I'm selling it. I've used it for practice at the driving range once a week and a few times on the course, so it has some signs of use, but I think it's in good condition. Please check the ONOFF official website for product details. Feel free to ask any questions in the comments!
