Abstract: A fly ball system comprising: a zipper assembly; a removeably-attachable tag having an eye; and an attacher removeably inserted through the eye. The zipper includes a zipper; a top tape extension; a top stop; a slider; a pull tab; a tape; a bottom stop; an insertion pin; and a retainer box. The zipper, the top tape extension, the top stop, the slider, the pull tab, the tape, the bottom stop, the insertion pin, and the retainer box form the zipper assembly for temporarily joining two edges of fabric together. The attacher includes a clip and is removeably-attached via an opening/closing mechanism to an interior cut-out located on a front portion of the pull tab on the slider of the zipper assembly. The attacher removeably-attaches the eye on the removeably-attachable tag to the pull tab on the slider of the zipper assembly for replacing existing broken zipper tabs.
