Briefcases are portable cases designed to keep papers and other work essentials together while they are carried. Their structured form helps protect and organize what is inside, and a handle makes them easy to transport. This collection includes examples identified as leather and aluminium briefcases, in black and brown, as well as open cases that show the hinged design. These materials offer different practical qualities: leather is flexible and durable, while aluminium is a lightweight metal often used for a more rigid case.
