briefcase

A briefcase is a flat, rectangular carrying case designed to transport documents and small personal items. It typically has a rigid or semi-rigid exterior, a hinged lid, a handle, and an organized interior for folders and accessories. Many models include locks or combination closures. Leather has long been the traditional material, but modern briefcases are also made from nylon, vinyl, aluminum, and other composites to balance durability and weight. The term attaché case is used for a formal, business-oriented version.

Origin and history: The modern attaché case developed in the late 19th and early 20th centuries, evolving from simple document boxes used by clerks and diplomats. It gained widespread popularity as a professional symbol in the mid-20th century, with advances in materials and security. Later designs introduced lightweight metal shells, plastic and composite bodies, and variants with wheels to aid transport.

Design and variants: Common features include a solid shell, a hinged lid, and multiple interior pockets for papers, cards, and pens. Sizes range from narrow 9–12 inch models to larger 15–17 inch cases. Variants include laptop briefcases with padded compartments and rolling briefcases with wheels and telescoping handles.

Use and culture: Briefcases are used by professionals such as lawyers, executives, and journalists to carry documents and electronics. They remain a symbol of work readiness and authority in many cultures. Care involves conditioning leather, cleaning fabric, and avoiding overpacking to preserve shape.
