It is semi-flexible, meaning you can draw thicker lines with more pressure. Use for Calligraphy, Manga, Cartoons and Art. Guaranteed to fit the Inkursive Manga fountain pen. These nibs are a generic brand so I cannot guarantee they will fit any particular brand of dip pen. These will not fit most fountain pens.
