SwingPerfect Golf Steel 17" Double-Sided Putting Mirror. Most putting errors start before you ever swing: open shoulders and drifting eye lines. This massive 17-inch steel mirror captures shoulders, eyes, and clubface in one unified frame.

"17-inch steel panorama: shoulders, eyes, and face perfectly aligned in one look."
"Dual-sided polished steel: unbreakable, unwearable, flip-ready tour precision."
"3-tier gate precision: a 1 mm start-line error gets flagged immediately."

1. Extra-Long 44cm Tour Profile (Full Stance Panorama): Nearly double the length of conventional 25cm acrylic mirrors; low address view captures both shoulders, eye line, and putter face simultaneously.

2. Dual-Sided Polished Stainless Steel (Unbreakable Lifetime Build): Precision-ground alloy steel with identical optical reflection surfaces on both sides; flip it over anytime for double the service life.

3. Deep Permanent Laser-Etched Guidelines: Target centerline, eye alignment markers, and shoulder squareness grids are laser-carved into the steel—never peeling, fading, or scratching away.

4. Integrated 3-Tier Progressive Gate Apertures (5/5.5/6cm): Insert two standard golf tees to create a narrow gate at exit; any 1° face-angle flaw is punished with an instant strike against the tee peg.

5. Weighted 380g Stance Stability with Royal Blue Leather Case: Heavy gauge steel sits completely flush and wind-resistant on green turf; slides into a tailored 46.5×14.5cm royal blue leather sleeve for bag travel.

6. OEM Ready — MOQ 100 Pieces Custom branding and OEM orders welcome with a minimum of 100 pieces — ideal for golf retailers, teaching academies, and practice facilities.

How to Use

Basic Posture Calibration

Lay the mirror face-up on your mat or the green (either side up — both sides are identical), T-legs pointing at the target, center line aligned with the target line.
Place the ball at the ball position in the T-leg channel, contact point aligned with the center reference line.
Address normally, look down into the mirror and check in order: ① target line aligned with the target; ② shoulder reference lines symmetrical and level; ③ eye-position line passing directly below the eyes; ④ eyes over the ball (eye position determines aim accuracy); ⑤ face square in the mirror.
Adjust posture on any problem, re-check in the mirror — repeat until the reflection matches the correct position.
For target-line assistance, insert tees into the face holes or gate holes to form a 3D guide (tees not included).
Putt normally; the ball rolls out of the T-channel: center line = correct; left = face closed or heel strike; right = face open or toe strike.

Gate Start-Line Training (tees not included)

Choose the target gate width: beginners 6cm, advanced 5.5cm, pro 5cm.
Insert tees (or spring gates) into the gate holes at the ball exit to form a physical gate.
Putt; a ball through the gate center = correct start line; tee contact = instant deviation feedback.
Once stable at a width, move to a narrower gate for systematic progression.
