Chartpak AD Markers are oil-based markers with a single nib that will produce three distinct line widths with a mere shift of the wrist. The unique nib shape gives the user precise control over each stroke, and colors blend easily when wet yet hold when dry. With color-coded barrels and caps.
AD marker sets contain a palette of 25 colors selected to meet your particular design needs. Markers are organized in a convenient caddy made of durable plastic.
