The cubicbag messenger small is made from 100% vegetable-tanned cowhide. It is worn over the shoulder using a long strap. The shoulder strap is made of leather and is attached in such a way that the bag is comfortable to wear. This messenger bag is suitable for work and leisure, and is especially suitable for bicycle transport. The messenger bag's distinctive and clean shape is derived from its folding principle. Empty, it is flat and can be stowed away to save space. When filled, the bag unfolds at the bottom. The flap folds completely over and is closed with two metal pull fasteners, making it almost watertight. The contents of the bag are thus optimally protected even in heavy rain, a feature that is particularly suitable for notebooks (up to approximately 11 inches) or tablets. The interior features an inside pocket for a cell phone, notebook, and wallet. On the outside back, there is a zippered compartment that extends across the entire surface of the bag. Its distinctive shape and functionality make the cubicbag messenger small a design object with high usability.
