Maintenance advice for technical pens

To store, seal with cap and lay horizontally or put in Pen-Station.

Nib and cap should be cleaned from time to time. You can use the professional rOtring cleaner fluid, available at rOtring.com, to clean the different pen parts.

When cleaning the Isograph, pull/twist off the push-on sleeve (if sleeve is stuck tight, use extractor in cap)

After cleaning, rinse all components with clean water and dry carefully.

Never disassemble the drawing nib as this will void the warranty.
