Since 1850, the German company Brause has been manufacturing steel nibs for writing, drawing and decorating. Brause nibs can be found in the toolbox of many calligraphers, artists, penmen and illustrators. This nib, also known as the, "Arrow” nib is smooth, highly elastic, and has a high ink capacity. Popular in Modern Calligraphy and Copperplate.
