STAEDTLERMars Matic 750 M013 Drafting Point - 0.13 mm

I've been using these pens since 1976 when I started work but just lately the very fine ones seem to give up the ghost overnight! I'm very gentle with them, use the correct ink, cap carefully when not in use but next morning, impossible to start. I'm in despair today because this 0.13 is brand new and I can't even get it going. A brand new pen! There are tears.

The nib units I purchased have been added to my stock against the possibility of them ceasing to be available. Its a shame that Faber Castelle no longer produce their range of pens and nib units and I suspect that the very sizes from the remaining manufacturers will be the first to disappear.

Ho acquistato questo accessorio insieme alla penna Mars Matic di Staedtler e sono molto soddisfatto. La punta da disegno è realizzata con ottimi materiali e molto ben progettata e costruita. Per me è un ottimo acquisto!

after trying everything it still will not draw a line , the inkt does not seem to let the ink throug . Have bought the ink cartridges but even that did not help. Can I send the compleet pen back?

Serve a mio marito per disegnare e ormai sono articoli tecnici che non è facile reperire nei negozi, anche quelli specializzati.Per fortuna su Amazon trovi tutto quello che ti serve. Grazie !!
