It flows well on the paper producing strong crisp lines and can be mixed with other colours, giving a cool dense tint. The inks can be diluted with water and used with brushes in traditional watercolour techniques or in dip pens, technical drawing pens, and airbrushes. The bottle has a pipette dropper in the lid which makes it easy to take small quantities from the bottle without wastage.
