Permanent marker, 1,4 mm, bullet tip, SHARPIE "Metallic", silver

The line thickness of markers depends on the design of the tip. As a result, there are types of markers, such as chisel-tipped markers, where the line thickness falls within a range rather than being a fixed value. On the other hand, cone-tipped and fine-tipped markers have a fixed line thickness. However, thicker cone-tipped markers can vary in line thickness depending on how we angle the marker and the pressure applied while writing.

The shape of the tip determines the line thickness of a marker and also influences its areas of application.
