2 Hole putting training mat + putting alignment mirror for honing your short game skills. Our standard edition mat features unique crystal velvet material that rolls just like a perfect green, alignment training lines to ensure straight back straight through stroke, and markings at 2, 4, 6, and 8 feet. This game changing putting mat is endorsed and used by the 2020 masters champion and world #1 Dustin Johnson. A few short minutes with this mirror on the practice green or standard edition putting mat will ensure a straight-back, straight-through pendulum stroke checking on your eye position over the ball simultaneously. Our putting mirror is a reflective, unbreakable mirror that shows you where your eyes are relative to both the golf ball and the putter face. The putting mirror has a slot for the golf ball as well as lines to indicate square relative to the putter face. Comes with convenient travel case.
