Precision Ball Alignment for Better Putting
This line liner lets you create a clear aim line on your golf ball, helping you square the putter face and aim exactly where you want the ball to start. When you stand over a putt, your eyes see a bold reference instead of guessing.

Snap-On Centered Holder
The round holder clips snugly around the golf ball and automatically centers it, so every line you draw is straight and perfectly aligned. No rocking, slipping or awkward balancing in your hands.

Multiple Groove Options for Custom Lines
Several grooves on the top and sides allow you to draw a main target line plus extra cross-lines or parallel lines. You can build your own visual system for putting, alignment and roll feedback without any complicated setup.

Two High-Contrast Marker Pens Included
The set comes with two fine-tip marker pens in different colours. Use one colour for your primary putting line and another for side marks, ball identification or extra alignment guides.
The fine-tip pens using oil-based, waterproof, fade-resistant ink, so your alignment lines stay sharp and visible round after round.

Instant Stroke Feedback on the Green
When you roll a putt, the line on the ball becomes a training aid. If it spins end-over-end, you know the stroke and face angle are solid. If it wobbles or snakes, you instantly see that something is off, making practice much more effective.

Useful for Tee Shots and Approach Alignment
Beyond putting, the marked line can help you aim your driver or irons. Set the line toward your target and match the clubface to it at address to start the ball on a more consistent line off the tee and from the fairway.

Durable, Lightweight Golf Bag Companion
Made from sturdy plastic, the compact tool and pens fit easily in any pocket of your golf bag. It’s light, simple to use, and always ready when you add a new ball to play.

Personalized Ball Identification
Unique colour combinations and line patterns make it easy to spot your ball in the fairway or rough. You reduce mix-ups with playing partners and always know you’re hitting the right ball.
