Brand new, never used, and the box hasn't been opened. Switching Master The photos are of a separate product being used as a reference. There are many tutorials on how to use it on YouTube, Instagram, etc. [Product Description] This is the world's first training device specifically designed for the "transition" in a golf swing. The design allows the center of gravity of the object to shift relative to the grip, teaching the correct direction of hand output during the transition, and "educating the hands" automatically. Just by clicking it, even those struggling with an early release can definitely master the desired "lag" in their swing.
