The film is in the form of a flat disc, and is fully housed in a plastic cartridge. There are 15 exposures, the disc being rotated 24° between each image. The camera is very simple to load and unload.
The format was introduced by Kodak in 1982, presumably as a replacement for their miniature Instamatic 110 format. The format did not really have any advantages compareed to its predecessors, and was not particularly successful. It was discontinued in 1998.
