thumb|An empty pocket boxA pocket box is a small box or pocket-sized container, so named to emphasise its portability.
In the 1980s pocket box was used by Steve Jackson Games to describe the (usually black) plastic boxes designed to hold a 4x 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.[1] The outside dimensions of a Steve Jackson Pocket Box are 4.25x.[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.
The term is also used generically by a variety of manufactures to describe the relative size of packaging for a variety of products.
Later editions were printed in a larger box.
In 2018, as a part of the Kickstarter campaign to bring back The Fantasy Trip, Steve Jackson Games created an updated Pocket Box container. In 2019, Steve Jackson Games ran a crowdfunding project to produce near-exact replicas of several Pocket Box games as well as associated ziplock bag expansions to those games.
