BIRDIE79 360-Degree Golf Ball Marker Alignment Tool Kit, 3 Pens, Gift Box | 360° & 180° Lines, 5 Alignment Styles, Triple-Line Design

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.

I use a standard sharpie but also used the pens that came with the product. The alignment tool is week made and I’m very happy with it as it just arrived and I was able to use it for my round today. Wasn’t line up the put with this. Only reason I didn’t give it 5 stars is the grooves are a little narrow for the pens. It’s a little difficult to get a good solid line without a lot of trying. But do recommend it.

Great for lining things up. Easy to use and precise. Worth the price. I gotta locate it now. Which friend borrowed it. Arg!!

I've been wanting one of these for awhile, finally pulled the trigger. Well by design you put a ball between the rubber caps on the inside, apply a little pressure on the two red buttons, that captures the ball and let's the marking barrel spin around the ball. The problem is a little too much pressure and the whole thing spins making it a frustration. I finally took some sandpaper to the outside where the barrel is next to the red button so when I squeeze the red buttons it does not pinch the barrel that is meant to spin. Works great now.

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.

I am very disappointed. Missing Essential Component The product appears to be designed well, but it cannot be used as intended because an essential component is missing. Since the training aid relies on all included parts to function properly, the product is incomplete and does not meet expectations.

Love this item,use it all the time

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

Does exactly what you think, the sharpies that come with are not good, they don’t last and smudge very easy, overall very happy

It does exactly what it's suppose to do. And it's inexpensive. Good product.

質感も良く、ボールに簡単にラインが引ける。 三本線や全周など好みでアレンジ可能。 色々試した結果、自分は全周1本線がいちばんしっくりくる。 今ではラウンドの際に欠かせないアイテム。
