5 1 4 zoll diskette
A CD in a square paper or plastic envelope is about the same size as a 5.5 inch floppy disk. I dashed down to the bins and rescued my 5.5 inch floppy disk box and now I have a nice neat way of storing my CDs. I even squeezed a few jewel cases in too. You can, of course, store anything you like in your old floppy disk.
