This ProMarker from Winsor & Newton comes with a black twin-tip marker and a blender marker which makes an excellent introduction to colouring and blending with alcohol based pens. Each marker has a dual tip with one being a brush nib for full precision lines, and the other a chisel nib to use for varied line widths. Promarkers use high quality alcohol based inks that are formulated using fine professional quality dyes. They give bold tonal ranges with flawless, streak-free coverage. Each ProMarker colour can be layered or blended on a variety of surfaces including paper, acetate, glass, wood or plastic. You don\'t even need to worry about smudges and blotching as they dry very quickly and are build to resist fading over time. - Brand: Winsor & Newton - Set of 2 - Black ProMarker + Blender - Twin-tipped markers with a brush and chisel nib - Can be layered and blended
