Media storage disk case
 The present invention relates to a disk case made of plastics material which comprises a case, body and a cover which can be snapped locked to the body to enclose a disk. The disk is retained by the body of the case by a snap button. The snap button has a lip which engages at the central aperture of the disk to provide a downward force onto the upward surface of the disk. The snap button is mounted on a flexibly ridged arm extending from the body of the case and allows for the snap button to be moved from an engaged to a disengaged condition with the disk.
