This is only the bottom of the enclosure for people who want to mix and match colors. It fits the latest AdaFruit 2500 battery, Intel Edison, and the Explorer board.
Note that this case has a storage location for a spare AAA pump battery. It is recommended to keep a battery in it, as it also acts as a pin to help secure the case together.
This bottom is available with or without the belt clip. Be careful flexing the clip as, while as strong as possible, it is possible to break it if you try.
