Faber-Castell Graphite Aquarelle Water-soluble pencils feature smooth water-soluble graphite. After drawing, simply use a wet brush to transform parts of your drawing into a wash, or dip the pencil tip in water before you draw, creating a rich, soft, and smooth line. These pencils are perfect for watercolor painting, sketches, and mixed media. The leads in the pencils are bonded to prevent breakage, and are varnish with an environmentally friendly, water-based varnish.The assorted set of 5 includes one pencil in each hardness, and a Faber-Castell No. 6 Round Watercolor Brush.
