The bullet shaped brush nib is made from a composite twin material that has fantastic wear properties. It is made up of a harder inner core and a softer outer layer. It’s a very versatile nib that enables the user to create a variety of strokes. Simply by varying the angle and downward pressure on the brush nib, the line width can be accurately controlled. The broad nib at the other end of the marker has a chisel shape, which is great for quick visuals and filling in larger areas.
