TEKUDAMA, a soccer ball specifically designed for skill improvement. This training ball, with the weight of a size 4 ball and the size of a size 2 ball, makes unpredictable movements. Supervised by professional soccer coach Toshiaki Miki. Made by SFIDA. Suitable for elementary school beginners, as well as junior high, high school students, and adults. TEKUDAMA looks like a regular ball, but its special structure, which changes irregularly, helps develop the ability to "move your body as you want," which is necessary for improving soccer skills. Just replace your usual practice with TEKUDAMA for activities like juggling, dribbling, and trapping! No special menu or instruction is required. Your body and feet will naturally start to move in response to the unpredictable movements. It's also popular with parents and coaches who don't have soccer experience and can't demonstrate techniques. ☆Thank you for viewing☆ Used only indoors. There is some discoloration and minor scratches, but it can be used without any problems. Please consider this item as a used product. If you are concerned about minor details or are very sensitive to the condition, please refrain from purchasing. The ball will be deflated and packaged, and shipped immediately.
