Jewel cases are the traditional option. They have three pieces – the lid, back cover, and media tray. When assembled, a case measures 5.59 in (width) X 4.92 in (height) X 0.39 in (depth). The front lid is clear and designed to hold booklets, which contain lyric sheets, liner notes, and more. The media tray is commonly black and removable, so a thin card may be inserted behind it to display things like copyrights and track listings.
