Most catalogues file this nib type purely under calligraphy, which undersells half of what it actually does. The bend in the nib means line width is controlled entirely by the angle you hold the pen at, not by pressure — which makes it functionally similar to the flexible brush-pens and dip nibs used in manga and comic inking, but in a refillable, no-mess fountain pen body. An illustrator can produce fine detail linework and bold, weighted outlines from a single pen simply by changing the tilt, which is exactly the kind of line-weight variation used to convey depth, speed, and emphasis in panel work.

Who is it For?
FREQUENTLY ASKED QUSTIONS (FAQ)
Is this the same as a flex nib?
No — a flex nib varies line width through pressure (tine spread), while the Fude de Mannen varies it purely through the angle you hold the pen at. They're different mechanisms and different skills; this one doesn't require any pressure control at all, just consistent angle awareness.
Can I use this for actual comic inking, or is it just for calligraphy?
Genuinely both. The same tilt-for-width mechanism that makes it good for decorative lettering is exactly what makes it useful for varying line weight in panel linework — hold it flatter for fine detail lines, more upright for bold outlines.
Does it use a proprietary cartridge?
Yes — Sailor's own cartridge/converter system, not standard international. Stock Sailor-specific ink alongside this pen at checkout.
