The cubicbag briefcase is made from original convertible top material as used in automobile production. On average, 80% leftovers from the production of convertible tops were used and 20% new convertible top material. The material is virtually waterproof, color-fast and dimensionally stable, i.e. it does not wear out. The briefcase can be carried by hand using the short handle or over the shoulder using the long, adjustable and detachable strap. The handle is made of leather. It has stitched edges and is fastened with two metal Loxx pull fasteners. A smaller zipped compartment is integrated on the front wall under the flap. A "toolkit" is attached between the front pocket and the first main compartment. A small additional pocket that can be removed using two press studs and has two small slip pockets and 1 small zipped compartment for a cell phone, notepad, pens, etc. There is another spacious, very practical zippered compartment on the back. The cubicbag briefcase impresses with its clear forms and functions. It has a discreet, high-quality, sporty look in terms of material and workmanship.
