This is a mini-size No. 3 basketball with a diameter of approximately 18 cm, made with the same authentic manufacturing method as TACHIKARA's competition-size model, in which synthetic leather is crimped onto the rubber layer inside the ball. The feel of the ball's surface and the bouncing power of the dribble are as good as the competition size model, and are reproduced in a mini-size ball. The No. 5 mini-ball (approx. 22 cm in diameter) is still too big for kids to handle, but it can be used freely as a playing partner for kids, as a signature ball, or as a collection ball.
