360-Degree Golf Ball Marker Alignment Tool Kit - Triple Line Stencil with 3-Color Pens and Gift Box

Super easy to use, well made, and designed compact enough to keep in your bag on the course in case you need to mark balls on the fly. Takes a few balls to get the hang of it, but it creates an awesome putting aid. Very similar result to a triple track ball which is a massive help when putting. I’ve marked probably 10 dozen golf balls so far and it’s creating crisp, accurate lines just like the first ball. You can keep the lines thin or thick, depending on your preference, and can use whatever color you prefer to mark the ball. I’d recommend going with the Milwaukee inkzall job site marker, which is very fast drying and much more permanent compared to a sharpie.

Great accessory for ball ID and setting up putting line. Results are quite professional in appearance as opposed to those free hand wiggly lines I've become accustomed to. Great Job.

When the ball is in the device, the caps where you hold the device are smooth, and it is VERY difficult to spin around the ball. If the end caps were knurled or grooved it would make it a lot easier.

The Birdie Liner is hands-down one of the easiest and most fun ways to customize your golf ball. The ease of use is top-notch—just snap your ball into place and get creative. Whether you’re lining it up for putting or just want to make sure your ball stands out in the group, this tool gets it done effortlessly.It comes with three color pens, which is awesome, but what really won me over is that it accepts Sharpies too. So if you’ve got your favorite color or brand already, you’re covered.With tons of marking combinations, from alignment lines to fun designs, your ball won’t just roll straighter—it’ll look good doing it. If you’re tired of mistaking your ball for someone else’s or just want to add some personality to your game, the Birdie Liner is a must-have in the bag.

Why did you pick this product vs others?:Works exactly how it is described. Holds the ball well and provides several options for marking. Light weight and easy to carry in your bag.

The device is harder to use than expected. You have to manually rotate the ball and by doing so the lines are not always consistent over the ball. Plus the ink smears. I have it all over the face of my driver.

Makes it easy to draw parallel lines on any ball to simplify putter alignment. The included red, blue and black markers work well to mark the ball. You can draw a variety of different line patterns to suit your mood.

This works as advertised. Many balls are coming out with alignment stripes already on them. But I will use this if it doesn't have one.
