Scope note:

Implements that use a reservoir of ink to make a mark or marks. A marker may have pointed or blunt tips, usually of fiber. It is distiguished from a felt-tip pen in that it typically makes a thicker mark than a pen and is more often used for labeling or marking rather than writing or drawing.
