Keep case

Standard black keep case

A keep case or poly-box is a type of packaging, most commonly used with DVDs and Blu-ray videos (and sometimes CDs).

Besides DVD-Video films, keep cases are very common with most disc-based video games since the PlayStation 2 although many modern systems use custom sizes, colours or molds and paint such as the Xbox Ones case, Blu-Ray discs also uses a one of a few custom Blu-Ray cases. Keep cases are also found on many PC titles (although many use CD Dual cases or thicker keep cases), and MP3-CD audiobooks (all use discs that are the same basic dimensions as a DVD).
