What is a technical drawing pen?
A technical drawing pen is specially designed for precision drawings where you need consistent line thickness. You use this type of pen for technical drawings, architectural sketches, graphic designs and other work where accuracy is essential.

Why choose a 0.25 mm line width?
The 0.25 mm nib produces very fine lines that are ideal for detailed work and smaller drawings. This line width allows you to add precise details without the lines becoming too thick, which is especially important for technical diagrams and detailed illustrations.

Rotring quality for professional use
Rotring is known for its reliable technical drawing pens that perform consistently. The Isograph series delivers even ink flow, ensuring uniform lines without interruptions while you draw. You can rely on the pen to maintain the same line quality even after prolonged use.

Practical usage tip
When using the pen, always pay attention to the correct angle relative to the paper for optimal ink flow. Store the pen horizontally when you are not using it to prevent it from drying out. The reference number 1903398 can be used when you need refills or replacement parts.
