Brand new, unused. Diameter: 24mm, Thickness: 1mm Includes 2 rubber belts. Additional belts are 100 yen each, so if you want more than 2, please comment before purchasing. These rubber belts are for opening and closing disc drives in CD players, DVD players, game consoles, etc. If your disc tray won't open, opens immediately, or has other issues, suspect the rubber belt is worn out (the photo shows a rubber belt replacement for an XBOX 360). It's recommended to choose a belt that is the same size or slightly smaller than the one you are replacing. Free shipping, delivered via anonymous shipping.
