These specialty inks are made by Herbin.

Herbin's calligraphy and specialty inks include rich metallics, shimmering pearlescents, and inks steeped in history.

These inks are not for fountain pens.

They are best suited for steel nibs, glass or quill pens, calames and brushes.

For fountain pen use, see Fountain Pens and Writing Inks.

Herbin also has a range of watercolour inks - see Paints and Specialty Inks category for these, as well as oil and pastel paints from Blockx.
