Important Product Notes

Minor micro-scratches from laser engraving and precision manufacturing may be present on the mirror surface; they do not affect functionality when viewed from standing height.
This mirror is single-sided — the reverse side is not designed for observation and will show manufacturing marks. Please consider carefully before purchasing if this is a concern.
Steel edges and drilled holes are precision-cut; handle and store with care to avoid contact with sharp corners or burrs.
After use in humid or wet conditions, wipe dry with a soft cloth and store fully dry to preserve the rust-resistant surface.

How-To Instructions:

Setup & Placement: Lay the mirror flat along the target line; place golf ball in the recessed U-slot on natural green turf or putting mat;
Eye & Face Alignment: Take address position; check that eye reflection aligns directly over the central longitudinal guideline, and align putter face flush with the laser lines;
Shoulder Calibration: Check the dual SHOULDER LINE reference bars to verify that shoulders and chest are strictly parallel to the target line, curing outside-in pulls;
Insert Tee Gates: Insert standard golf tees into front gate holes for your target difficulty (5.0cm baseline, 4.8cm advanced, 4.5cm tour precision);
Execute Stroke: Make a smooth pendulum stroke, rolling the ball cleanly through the tee gate without touching either tee.
