The set consists of eleven Blue Optima
Auroloide with gold trim fountain pens. Each pen has Calligraphy
engraved on it followed by the tip size.
Just like Pelikan nib units, these Aurora
nib units can be interchanged by you at home. The table below
shows the width and the height of each tipping surface. Notice
that in the case of the Oblique, Stub and Italic nibs
the width is much greater than the height. This provides the
line width variation that so many of us like. These 14K nibs
are suitable for added flexibility customization ($65 extra).
