The simplest is the C-shell or clam shell type.  The disc is clamped securely inside it.  The disc print can be seen through the shell and so you don't need additional artwork. The robust nature of these cases makes them economical for posting to clients, as they should require minimal additional packaging to make sure that the disc arrives undamaged.

An alternative is the jewel case (similar to those used for CDs). This is easier to store on a shelf and because the front is crystal clear the disc print can be seen from outside and no additional artwork is needed. There are, however, clips so that you can insert either a card or a small booklet in the front of the case, should you so wish.  There is also provision for a "back and spine" insert if required. This can be used to give details of what's on the disc - title, performers, production credits, track information, etc. Slimline versions of the jewel case are also available.

Greater sophistication comes with the library case.  This can be either a single disc case or, with the addition of various "flaps", be a multi-disc case.  There are clips on the inside front to hold a booklet if required.  An insert is required for the library case which is held within a clear sleeve.  See below for details.
