“Sonnet” TWIN BRUSH Markers are intended for all types of sketching, as well as complex illustrations, comics and other creative directions. They are are twin-tipped with brush and chisel on the sides, allowing illustrators and sketchers to work with a flexible brush nib that is resilient, easy to control, and allows you to vary the stroke from fine lines to wide strokes, to achieve soft colour transitions. The chisel is suitable for fast visualization and filling of large pieces of work. The supply of ink markers is controlled, uniform. Semi-transparent colours blend well and are superimposed on each other with glazes, forming smooth gradients and new shades..
