Dr Ph Martin's Pen-white

Dr. Ph. Martin's Pen-White is perfect for fine writing, though it was made to be used in technical pens and airbrush. We suggest that you pour a little quantity in a dinky dip and add some water drops. This liquid product delivers the same brightness and permanency of traditional watercolors in tubes, but is much more versatile and easy to use.

The color is incredibly opaque and can cover dye and marker color. Flows through a 3x0 (0.25 mm) pen tip. Comes in a 1.0 oz (30ml) glass bottle with dropper.
