SwgPerfect Golf Putting Straight Line Training Board Carbon Fiber 3-Pack, Wide Medium Narrow Difficulty Indoor & Green Practice Aid. Every putt is fundamentally a straight putt! Progress through 3 stepped carbon rails: roll the ball along the edge—the instant it drifts, it drops off, engraving tour-level start-line accuracy into muscle memory.

• "Every putt is a straight putt. Train the line, make the putt."

•  "See the miss the instant it happens — then fix it for good."

• "Three rails, three stages: from your first straight putt to your last."

1. Progressive 3-Tier Difficulty Progression (Wide/Medium/Narrow): 4cm wide rail builds initial straight-line confidence; 2cm medium rail locks in path consistency; 1.5cm narrow rail challenges tour-level precision. One kit covers your entire game progression.

2. Instant Visual & Tactile Roll-Off Feedback: Stroke along the board's edge; rolling off to the left immediately exposes a closed face, while falling to the right proves an open face—diagnosing and fixing stroke flaws in seconds.

3. Eliminates Green-Reading Distractions: Removes slopes and break variables, leaving only start-line squareness and tempo to master, keeping launch line error strictly within 0.75°.

4. High-Grade Lightweight Carbon Composite (184g Total Kit): ~30% lighter than ordinary plastic trainers; 0.2cm ultra-thin profile stays perfectly flat on green grass without warping, ensuring true, bounce-free roll-off.

5. Dedicated Protective Leather Travel Sleeve: Custom-tailored 52×6cm scratch-resistant leather pouch houses all 3 rails securely; slips effortlessly into any golf bag pocket for practice anywhere.

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.
