The document discusses the format and design of digipaks. It explains that digipaks fold into a square case and can have various panel configurations. The front panel is the main promotional piece, typically featuring an eye-catching picture and the song or album title. The back panel is also used for promotion. The inside contains the plastic CD holder and additional information about the artist and album. The example digipak discussed uses a candy theme and images of the artist Katy Perry, both naked and clothed, to promote her album throughout the packaging in an attention-grabbing way.
