The mummy case is composed of a substance known as cartonnage, which is linen or papyrus strips that have been bound together with a gummy substance in order to form a flexible shell.

The case is covered with paints that were made up of mineral and vegetable substances. The paints were applied with a reed brush.

The face on the mummy case is not of the dead man, but is a generalized human face.

Images on the mummy case reflected events which Paankhenamun hoped would carry him into the afterlife.

Gods depicted on the case include Horus, Osiris, Isis and Nephytes.
