Putting an alignment line on a golf ball has proven to be a tremendous aid in sinking more putts per round. This "Line M Up" Standard Model makes it easy to get a precision line where you want it on the golf ball. The line-guide snaps over the ball and holds it securely in position while you draw the line. A full size, long lasting Sharpie pen is included. A FREE "4 Yards More" golf tee is included also while supplies last. Available colors are assorted, usually Blue, Green, Red or Black. We'll ship one of these unless you indicate a color preference when ordering.
