This is a non-slice tee that helps to reduce slices and hooks. (The tee is the same white color as the ball, making it less noticeable.) Includes two adjustable tees for peace of mind in case of loss! The total length is 80mm, and the actual height of 25mm may be a bit low, so please use the adjustable tees. If you're struggling with slices and hooks even after changing your swing, please give this a try. It's a great product that can solve the problem without changing your swing. Featured on UUUM Golf YouTube's Namiki Laboratory and also introduced on YouTube by many others! For those with a swing speed of 45 or less, or those whose club isn't entering straight, it can also lead to increased distance by reducing spin. Because it doesn't directly touch the ball, the spin caused by the club's entry is significantly reduced, making it harder to spin and curve the ball. With this product, you tee up the ball as shown in the fourth image, and then hit the plastic surface of this product. The cause of slices and hooks is the friction between the ball and the face of the club, which creates spin and causes the ball to curve. However, this product goes between the ball and the club face, physically preventing the ball from being rubbed, resulting in reduced spin and less curving. Size: Total length 80mm, Height 50mm Slice Tee: 10 pieces (white) Adjustable Tee: 2 pieces (red and blue) *Using the adjustable tee increases the height from 50mm to 70mm.
