What is a Monoline Pen?

At its core, a monoline pen is a type of drawing instrument known for producing lines of consistent thickness. Unlike its pressure-sensitive cousins that change line width based on how hard you press, the monoline pen keeps it simple: one pressure, one line width, no drama.

Why Monoline Pens are Special

The consistent line width makes these pens perfect for projects where uniformity is crucial. Think of precise technical drawings, minimalistic art, or elegant script lettering.
