Danact (for golf) This is a putting rail training device. It functions as a guide for developing a straight stroke. It has been developed with a focus on high-quality materials. It allows for a 1-meter putt check, helping you understand your putting tendencies. You can place the ball in the hole and practice at home. The product itself has no noticeable stains, but the case has some. Length: Approximately 92cm (measured by an amateur) Please refrain from purchasing if you are concerned about minor details. Due to the length, shipping costs are high, so I am not considering a discount.
