This invention provides a padfolio, portfolio, case, bag or other business accessory that carries, on an exterior surface, a pocket flap that is typically open at the top edge and joined at a bottom edge. It has a size sufficient to completely cover a predetermined range of conventional documents (or other items), and in one embodiment, has side walls that taper from a wider bottom that may be longer than the predetermined documents to a narrower top that is typically shorter than the predetermined documents so that the side edges of the predetermined documents are at least partially visible to evidence their presence in the pocket. A narrow elastic strip joins each of the opposing side edges to the exterior surface at a location along the exterior surface that is outboard of opposing edges of the predetermined documents so that they may slide into the pocket free of interference for the joint between the elastic strips and the exterior surface. The tension generated by the strips is, however, sufficient to maintain holding friction, via the pocket flap on the documents, but enables expansion of the flap to admit thicker items when desired, including machinery for providing decoration to the flap. In an illustrative embodiment, the strips may be less than one half the total length of the side edges.
