With the carmine Talens Ecoline liquid watercolour, you can create the most beautiful creations. The watercolour paint is ready to use, not waterproof, and adheres well to watercolour paper, drawing paper, and cardboard. The Ecoline paint comes in a 30ml bottle with a handy pipette in the cap. Using this pipette, you can accurately dose the Ecoline while mixing. The opening of the bottle is wide enough to dip a brush or dip pen into.
