YONEX TP-01 Tri-Principle Putter This putter gained popularity with the claim that "1-meter putts go in with a probability of over 90%." Due to the large head, you can stroke it roughly in a good way, and it gives the impression that you can hit within a large sweet spot. The original 36-inch length allows for an upright stance, enabling stable performance. As shown in the photos, there are minor scratches on the face and other areas from normal use, but overall, it's in good condition. The Golf Pride grip in the photos is new. Includes the original head cover (with some stains).
