EyeLine Golf Ball Liner By Hank Haney-Pack of 3 (Red)

Transfer your practice to the course with the ball liner. Unlike any ball liner on the market, this one has an added line that is parallel to the putter face so that you can visualized the "flat" surface. Line up your ball to the target. Focus your attention on the black line, and put your putter on this "flat" surface. Make a confident stroke delivering the putter face squarely to the back line... and listen for the ball to drop.
