Rotring S0699390 ISOGR COLL ST .2. .4 .6

Achieve consistent, professional line work for technical diagrams, security plans and surveillance schematics with the Rotring ISOGR technical pen set. Designed for engineers, CAD technicians and security professionals, this set delivers precise control with three pen point sizes—0.2 mm, 0.4 mm and 0.6 mm—so you can switch between fine detail and bolder outlines without changing tools. The pens ship in assorted ink colors and use non-erasable ink, making them well suited to secure documentation, monitoring logs and official schematics that require permanence and clarity.

Because the ISOGR pens are non-refillable and ready-to-use, teams benefit from lower maintenance and predictable performance on the job, whether drawing site plans, annotating surveillance layouts or producing network diagrams. The ergonomic body supports steady strokes and reduces hand fatigue during extended sessions. Backed by Rotring’s reputation for precision instruments, these technical pens help professionals produce accurate, presentation-ready work faster.
