Pilot Parallel Pen as a Highlighter
Sometimes we get customers who tell us they use their Lamy or TWSBI 1.5 italic nibs as highlighters, filling them with a highlighter ink like Noodler's Firefly, or another light ink. 1.5 is a pretty broad nib for writing, and you can get some good calligraphic action out of it, but you can also consider using a Parallel Pen if you're ready to get serious about your highlighting.
