Speedball pen nibs, suitable for left-handed calligraphers.

The C-series pen nib was introduced in 1918. It features a traditional broad edge with a great degree of flexibility and is the most popular of the three broad edge offerings. It's meant to be held at a constant angle throughout, with minor variations needed depending upon the lettering style.  This consistent angle gives the lettering artist the desired thick and thin strokes usually associated with broad edge calligraphy.
