Isomars Ruling Bow Drawing Pen Liner

An Isomars ruling pen is a technical drawing instrument used for creating lines of precise, consistent thickness with ink or thinned paint. It features a metal nib with two adjustable jaws controlled by a screw, allowing for line width adjustment. These pens are commonly used in engineering, cartography, and other fields requiring accurate and detailed technical drawings. A guide video for using the pen, and another video.
