Birdie Liner Black Golf Ball Marker Alignment Tool Kit - 360-Degree Triple Line Stencil with 3-Color Pens and Gift Box - Premium Quality(Black)

Great ball marker, this puts a perfect lines all round my ball, which has improved my putting as I can see the roll of my put perfect.

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

The tool Alignment Tool is great. The pens not so much. The pens are'nt permanent so the lines end up smudging, getting on your hands, the inside of your bag and on the club face.

Very handy item

Ok but pens are useless

It worked well on the 3 initial balls I marked up so will get used over the coming season and hopefully improve my putting. The 3 coloured pens are small but work fine, these will need replacing at some point depending on how many balls I lose and need to replace and mark up.

Not as described, no marker pens or gift box included. Absolutely rubbish

Excellent little gadget. Very quick delivery. Thanks

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

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。

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

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.

Love how it helps set up
