Portable multi-purpose product

Briefcases are light in weight and excellent for organizing small things. The briefcases are upholstered and used for measuring instruments, microphones, product presentations and other small objects. The briefcases can be piled, stored inside of a trunk case or on a storage shelf. In addition to traditional plywood the briefcases can also be manufactured using rotomold technique, which makes the case water- and dustproof.
