2024 model. Purchased new for around 55,000 yen and used for about a year. This is a special Ai-ONE MILLED model, which has an even better feel than the standard Ai-ONE model. It has a very sharp and refined shape, and the double bend neck makes it easy to aim straight at the target. I loved it, but I'm selling it because I bought a new putter. The grip has some dirt, but there are no problems with its use. Please check the photos for scratches and dirt. You definitely can't buy this at this price if you were to purchase the same item at a used shop. Please check at the store. If you are interested, please consider purchasing it.
