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.

Works well. Recommended to me by my 14 year old grandson who is an excellent golfer!

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.

Great Product to line you golf balls up when you get used to it ( hard at first but when you get it the first time you’ll get the hang of it)

Does exactly what it should. Love this as it helps to line up puts for greater accuracy. Also like that it can help with my tee shots as well buy pointing the lines in the direction (if I plan on a fade or draw). The durablity is great and design is nice. you can do half the ball or rotate for a full circle.

The BIRDIE79 Golf Ball Marker Stencil does what it’s supposed to, providing 360-degree alignment with clear markings, but it feels overly complicated and expensive for what it is. While it comes with a nice gift box and marker pens, there are plenty of cheaper options on the market that offer similar effectiveness at a fraction of the price. Overall, it works as advertised, but I’d recommend looking for a more budget-friendly alternative if you're not set on the extra features.

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.

Only giving it a 4 star for the simple fact that they have the material as "iron". Its not metal, it is plastic. There are other identical ones you can save a few dollars on. That being said tho it's still nice. Ball fits in nice with rubber grips to hold it and it allows you to spin the tool around the ball on the grips to make perfect 360 degree lines if that's what you like. Nice line thickness as well, not too thin and not too thick like other ball markers.
