Versatile nylon-tipped brush allow you to fill the barrel with any water-soluble medium (water-soluble inks, watercolours or gouache) to use for lettering or painting.
Alternatively, you can just use water and pick up watercolour or gouache colour from your palette to create great wash effects. Control the density of colour by squeezing on the barrel of the brush pen to make the brush wetter or drier.
