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" Pro Model makes it easy to get a precision line where you want it on the golf ball. The Pro Model line-guide has multiple marking options instead of just a single line. This allows you to find the most helpful marking. The line-guide snaps over the ball and holds it securely in position while you mark the ball. Included is a Mini-Sharpie pen attached to the line-guide. 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.
