Thank you for viewing. The yellow one was used once, but the green one has not been used. I am selling it because I no longer need it. 《Product Information》 BBCH Pitch Trainer Band Set of 2 A new training tube has arrived with a real-size (7.2cm diameter) and weight (approximately 140g) hard baseball attached to the tip! A carabiner is attached to the opposite side of the ball, so you can have a practice partner hold it, or you can fix it to a fence or net to practice pitching, train your inner muscles, and strengthen your forearms, elbows, and shoulders even by yourself. Players working on correcting and improving their form can check and review their pitching form while applying the appropriate load, not just shadow pitching. ■ Realistic throwing sensation: The ball at the tip reproduces the size, weight, and texture close to an official ball. You can use the throwing motion as it is for training without losing the actual throwing sensation. ■ High-durability material: Durable tube material is used. It is resistant to deterioration even with repeated use and supports long-term training. ■ Compact & Portable: Lightweight and compact design allows for easy training at home or in the yard, as well as during warm-ups before games, and even when traveling or on expeditions. ■ Because it is a ball shape that is easy to grip, it can be applied to various sports other than baseball. ● Strength Guide: ・Yellow (Weak) / Approximately 4.5kg ・Green (Medium) / Approximately 9kg ・Red (Strong) / Approximately 13.6kg ● Size: Total length / Approximately 124cm, Tube part / Approximately 106cm Ball / Diameter approximately 7.2cm, Weight / Approximately 140g ● Materials: Latex, PP, PVC
