The Hiro Leonardt 41 is a very flexible nib. It is also regularly referred to as the crown pen.
The crown pen is made of steel and has a crown-shaped widening, where this nib got its name. You stick the pen into a pen holder to use it. The strange idea that this type of pen was used as standard until the 1960s! Now you can create the most beautiful works of art with Modern Calligraphy.
