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

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.

I use this to draw alignment lines for putting. The markers included are decent quality but the tool itself is top notch. Looks just like a triple track ball when finished. Great value, small size, accurate lines, and easy to use. Plus you can customize with any line color you like.

I have played the callaway triple track balls since they first came out, I do have a odyssey triple . Over the years my game has changed enough that I find other balls better. I was playing tp5x for awhile then switched to Srixon balls. Regardless of what ball I choose to play I can easily put on the lines in just a few minutes. The only knock on this is the markers SUCK! The lines barely make it through a round. I found that Sharpie Pro Markers last longer. Regardless of marker it will leave paint/marker transfer to your clubs. Cleans easy off of irons but will need a stronger cleaner. I've tried alcohol wipes on the course and a light strength paint remover at home if needed. Some people might not care but, I work hard for my money and I want my stuff to look good and last.

Great tool and easy to use.

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.

The Liner comes from Korea. The pens come from China. This is not disclosed on the Amazon site. If you want a line(s) that surround the entire ball, this devise works easily and well, this Liner is for you. The ball is held firmly by the Liner at the top and bottom of the ball. The cut outs for the marking lines are attached to the Liner body and (can) rotate around the ball. If you don't need a line(s) that goes around the entire ball, there are Liners available for less than half the price of this one. An advantage of this Liner for a line that surrounds the ball is that the line is easy to draw and in the center of the ball and parallel to all the lines if you draw 3 lines. The pens work. However, you get the feeling that they do not have a long life. But they did work.

The Birdie Liner Alignment Tool is fantastic for improving putting accuracy. The design and five line options make it easy to draw precise alignment lines on your ball. The triple-track lines really help with consistency and aim, especially on the green. For the price, it’s a great tool!

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.
