This is a plastic CD case that can hold 11 CDs. - Quantity: 11 pieces - Material: Plastic - Type: CD case These are slim, empty cases that can be used for CDs, DVDs, and Blu-rays. All are clear (the back has a slightly frosted glass texture), and this is a set of relatively clean cases selected from among those I was using. The size is the same for all, but I think the manufacturers are probably different. I will send them as a set of 11.
