The water tank brush is an essential tool for every artist. The bristles are made from high-quality synthetic fibers. The cap can be used for scratching and scraping techniques. The water tank has a capacity of 6 ml, making it practical for mobile use on the go. It is ideal for glazing, wet-on-wet, and dry brush techniques (granulation). By gently squeezing the body of the brush, water flows to the tip. It works excellently in combination with watercolor pencils and water-soluble paints, such as watercolor paints in pans or tubes.
