The cubicbag briefcase is made from genuine convertible top fabric, as used in automobile production. On average, 80% "leftovers" from convertible top production and 20% new convertible top material were used. The material is virtually waterproof, colorfast, and dimensionally stable, meaning it won't stretch. The briefcase is carried by hand using the short handle or over the shoulder using the long, adjustable and removable strap. The handle is made of leather. It has stitched edges and is closed with two metal Loxx pull fasteners. A smaller zippered compartment is integrated into the front panel under the flap. A "toolkit" is hung between the front pocket and the first main compartment. This small additional pocket can be removed with two snap fasteners and offers two small slip pockets and a small zippered pocket for a cell phone, notepad, pens, etc. On the back, there is another spacious, very practical zippered compartment. The cubicbag briefcase impresses with its clear shapes and functions. It has a subtle, high-quality, sporty look in terms of material and workmanship.
