The COPIC Sketch marker, with the Super Brush nib, is perfect for doing professional illustration, fashion design, Manga, and adding detail to your images. The Sketch Super Brush nib acts like a paintbrush both in feel and color application. This double ended marker provides two unique tips in one marker! For more control, use the Medium Broad nib on the opposite end of the marker. Sketch markers work with the airbrush system, and their nibs are replaceable.
