Brause nibs can be found in the toolbox of many calligraphers, lettering artists, penmen and illustrators. They are famous for offering a subtle balance between relative elasticity for easier writing, and the resistance necessary for clear strokes.
The Plakat 5mm #75510 is a gold-plated, folded, steel nib for large letters.
Brause Nibs are manufactured in Germany from cold rolled steel and pressed with tools specific to each model and nib size.
