Royal Tees Deluxe are considered the first fully flexible golf tee designed to give greater consistency and extra yardage to your drive. These tees are made from a completely flexible rubber that moves away from the ball on impact, reducing resistance and spin, giving you longer and straighter drives. Any regular tee will fit and work perfectly. Just dampen the base and the tee will slide in easily. Another great advantage is the consistent ball height. This takes out that extra variable in your swing, allowing you to be more consistent and have greater confidence in your game. The set of Royal Tees (set of 3, 1", 1.5", and 2") comes packed inside a genuine leather pouch.
