BIRDIE79 360-Degree Golf Ball Marker Alignment Tool Kit 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.

Absolutely loved this! Nothing worse than going to a course with someone as the same ball as you, don’t know what number ball you hit. This is such a COOL way to make your balls your own. So many different designs you can choose from. Had so much fun doing this. I ended up doing 11 balls balls and they DESTROY your permanent marker so just be ready. Start with a fresh one and go to town. The markers they give are decent, only used them on one ball and worked fine, seemed little more wet than the sharpie brand permanent marker. Will mark all my balls from now on.

Met expectations to a certain level but I am not sure I would buy it again.

My dad told me that I should get this and mark my balls. He said that it would help me better align my clubs when I hit. After some work and a few rounds I noticed that I was hitting the ball better and cleaner and it helped me focus my swing at the point of contact. I believe that it has helped me drop a couple strokes off my game. Not a lot but just enough to have more bragging rights at the end of the day in the 19th hole bar.

Ball marker is easy to use and the start of a great idea. Meaning, the markers are garbage and not really permanent. Are one round, the lines are pretty much gone and my markers dried out really fast. Aftermarket markers are too wide and really can't be used.

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.

Easy to mark my golf ball.

Surprisingly well made little piece of plastic that will help you mark your balls. Whether or not that's important for amateurs, we'll, that's another story.

使いやすいですが、 3色ペンは入っていないので注意してください。 ですので、他の類似商品と比べて割高です。

Se me hizo practico para marcar líneas en la pelota que te ayudan a alinearla al objetivo, y no se limita a solo la mitad, tiene unos como rotores que hacen que se mueva y las líneas lleven continuidad alrededor de toda la pelota

Awesome item have already bought a second one for a friend.

Great product very easy to use saves loads of money instead of buying balls with lines on them highly recommend

This is a helpful tool for putting .
