Abstract: A golf ball designed for practicing indoors. The golf ball comprises a soft-shelled flexible hollow spherical cage, a stitched hollow spherical cover enclosing the hollow spherical cage and granules enclosed in the hollow spherical cage. The spherical cage comprises a plurality of holes on its surface. The spherical cover is made by stitching a thread into a hollow spherical shape. Before closing the spherical cover, the spherical cage is inserted into it. The granules are then inserted in the spherical cage through the holes in its surface. Following which, the spherical cover is completely sealed by further stitching the thread.
