Product details are as follows: ### Main Effects of Kiredas • Stable Release Point: If you don't throw correctly, it will flip over or lose speed, so your body will learn the point where you apply the most force. • Improved Spin Rate: It cultivates the feeling of "cutting" the ball with your fingertips, so it's said to increase sharpness when you return to throwing a real ball. • Injury Prevention: It helps to eliminate "hand throwing" (throwing only with your hands) and is expected to improve your form to be more efficient using your whole body. ### Usage Advice 1. First, use the normal version and check if you can throw it straight and stably at a distance of about 10 meters. 2. Once you can throw it cleanly, switch to the Athlete version and focus on a stronger "push," which is a smooth step-up. This is "Version 2" with fins that have 120 times the durability of previous models. 【KIREDAS (Kiredas) Product Lineup Comparison】 ■ Kiredas Normal (White Box / Yellow Fins) • Target: Beginners, juniors, those who want to build a solid foundation • Features: An entry-level model to grasp the correct release point.
