Dr Ph Martins Pen White Ink

Dr Ph Martins Pen White Ink is an opaque white ink designed for use in technical pens, dip pens and airbrushes. This ink offers the same brightness and permanence as traditional tubed watercolour paints, but is much more versatile and easier to use. Pen White Ink is incredibly opaque and can cover both dye and marker colour. It is ultra fine in consistency and is perfect for fine writing. This ink is not waterproof and will flow through a 0.25mm pen tip.
This ink is pigment-based, archival grade, non-spreading and has a dropper top.
