“A gold pen and rubber holder containing ink for several days’ writing. ….. A luxury for persons who care to preserve their individuality in writing.”
Dipping a gold nib in ink allows one to write with line variation and individual personality. Stylographic pens, or ink pencils, had internal ink reservoirs, but lacked the ability to write with any line variation. c1880-1885, Mabie Todd produced the Calligraphic Pen, which used a wire feed in the style of a stylo and brought the wire through a gold nib. The wire ends on top of the nib as a coiled overfeed.
