In the 1980s pocket box was used by Steve Jackson Games to describe the (usually black) plastic boxes designed to hold a 4-by-7-inch (10 cm × 18 cm) rulebook and related game components.
They replaced ziplock bags previously used for the same games.
Steve Jackson Games also sold empty Pocket Boxes for holding extra components or repacking other microgames.
[2] Pocket Box is also used by Haba as the brand name for its small pouch designed to hang from a belt and hold a cell phone.
In 2018, as a part of the Kickstarter campaign to bring back The Fantasy Trip, Steve Jackson Games created an updated Pocket Box container.
