Mizuno Pitching Training Baseball Better Spin Purchased several years ago. You can easily train by watching TV or YouTube. It changes the feeling of holding the ball to the image of hooking it, so if it fits well, your ball speed will increase. Also, by flicking with your fingers at the end, you can also cultivate the feeling of release. I think it's a good training tool because it improves the sensation in your fingertips. There are some scratches (peeling) on the base. Because the frequency of use is extremely low, the condition of the spring and other parts are in good condition.
