Speedball India Ink

Speedball describes Super Black India Ink as waterproof once dry. It is made for calligraphy, illustration, and other work where a permanent black line is useful. [Speedball](https://www.speedballart.com/super-black-india-ink/)

The Super Black formula uses highly opaque carbon-black pigment. Speedball says it is intended for good reproduction quality on absorbent surfaces and offers strong lightfastness. [Speedball](https://www.speedballart.com/super-black-india-ink/)

The manufacturer's listed tools are brushes, pens, steel brushes, and airbrushes, rather than refillable fountain-pen filling systems. A dip pen or drawing pen is the safer match because waterproof pigmented ink can create cleaning and clogging problems in a fountain-pen feed.
