Water Tank Brush is ideal for outdoor work, there is no need to bring containers with water and countless brushes! The water supply in the container is supplied to the tip of the brush through the valve, which gives a constant flow of water when the bristles touch the paper. The brush can be filled with ink or liquid watercolor eg ECOLINE and used as a brush pen.
