BIRDIE79 Premium Quality360-Degree+180-Degree Combined Birdie Liner Drawing Alignment Tool Kit- 360-Degree Triple 3-Line Golf Ball Marker with Wrapped Luxurious Gift Box Including 3 Marker Pens

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.
