Good Calligraphist, Designer and Cartoonist pen
This pen is good for Calligraphy, Architectural designs, Cartoons or Designs Pros: No Ink blotting even when making very close lines together The flow is good Built quality is good. Re-fillable The cap is also screw based. Cons: Costly Ink from Rotring is costly. (I am using currently Parker Quink = Rs 50 only) Delicate Nib Old style design. Boring looks One need to be very cautious while lending this to someone who is not good with pens Overall, this is a superb pen. Parker Quink can be used as well for a smooth and smudge free writing. Rotring Ink would be best (but not easily available in stationary shops). PS: .25 Nib is very small for regular writers. They should go with Min .35 or above.

Je les utilise depuis des décennies, super qualité. Par contre utilisez l'encre Staedler car l'encre est plus fluide que la rotring tout en étant indélébile

Pen consistently lays down a fine line. I’m using the Rotring ink and the pen has not clogged even when sitting unused for several weeks. I use it for sketching and watercolor highlights. It’s great for small drawings where I need detail with a very fine point. As others have said, this is a technical pen, and must be used fairly perpendicular to the paper. Once you grow used to that, it’s great.

These are much better at keeping the ink from drying out than other brands that I've tried. I have 2 sizes now and probably will order another one.

Ich schreibe im Studium extrem viel und nach einem Jahr Rapidograph habe ich mit einen Isograph gekauft, weil ich den Rapido nicht mehr in Gang bekam, trotz aller Reinigungsversuche. Isograph funktioniert zuverlässiger und kann wirklich komplett zerlegt werden. Auch gelingt mit das Nachfüllen des Iso wesentlich besser als der Patronentausch des Rapido. Selbst nach 2 Wochen Pause schreibt der Iso in kürzester Zeit wie vorher, hohe Zuverlässigkeit.
