Am-Dig Tin DVD/CD Case Square Style Hinged, with Window, Blue Tray, Deep Hub - 10 Pack High quality tin is used to make this case giving it a unique look that is more durable than any plastic case. A clear plastic window with a 4.5" (115mm) diameter allows your disc to show through. The light blue tray comfortably holds up to 3 discs (5 if the media is thin enough) in a stacked formation. The tray can be removed easily. This allows the case to be used for purposes other than optical media storage. DIMENSIONS**: 5.7" x 5.1" x 0.5" (145mm x 130mm x 13mm)
