Product Description Sketch markers come in the widest range of colors, and feature the Medium Broad and Super Brush nib combination. The responsive and flexible Super Brush nib delivers a wide range of marks and makes blending easy. The Sketch marker has revolutionized fine art markers. The Super Brush nib feels like a brush-a saturated, flexible brush that never frays and is long lasting. It allows artists to spread ink in a smooth, water color like way. The other end has a Medium Broad nib, which is a firm chisel tip perfect for airbrushing and coloring large areas. Sketch markers are commonly used for comics and storyboard illustration, fashion design, interior design, manga and anime, landscape architecture, rubber-stamping, mixed media arts, tattoo arts, calligraphy and more.
