For whom is a technical drawing pen intended?
A technical drawing pen such as the Rotring Isograph is used when you need to draw or write with extreme precision. This type of pen is indispensable for technical drawings, architectural plans, graphic design and precision work where every line must have exactly the right thickness.

Why choose the 0.10 mm variant?
The 0.10 mm line width is the thinnest variant in the Isograph range and ideal for very fine details, dimension lines and thin construction lines. You choose this width when you need extremely precise, thin lines that should not dominate your drawing but must still be clearly visible.

What makes the Isograph special?
The Rotring Isograph works with a DIN-standardised drawing system that ensures a constant line width, regardless of the drawing speed or pressure you apply. The pen offers easy maintenance thanks to the patented tube insert, which allows quick interim cleaning.

Practical use and maintenance
This pen has reference number 1903394 (formerly R151010/S0201850). Always store the pen horizontally or with the tip facing down to prevent it from drying out. Regular use keeps the ink flow optimal, and during longer periods of non-use you can immerse the tip in lukewarm water to prevent blockages.
