Abstract: The present invention provides a detachable organizer with a fastener for securing the organizer closed and/or for securing the organizer to a target surface, such as the interior surface of the closure flap of a flight case or a litigation briefcase. Alternatively, the organizer can be secured to a wall, countertop, desktop or dashboard or the like. For use by aircraft flight crew personnel, the interior of the organizer comprises a plurality of pockets adapted for receiving and securely holding small necessary items, including passport, small pocket calculator, flight log and expense record, pens and/or pencils, mini-flashlight and the FAA-approved folding multipurpose tool unit (e.g., the Leatherman tool). The preferred fastener by which the organizer is secured closed and attached to the target surface is hook-loop material, and preferably the organizer can be reversibly secured to the target surface in the closed or opened configuration.
