I bought a Graf von Faber Castell Classic (Pernambuco Wood) fountain pen earlier this year new. I wanted a pen for air travel that had cartridge filling but also had a piston or similar filler system for more economical use when not travelling. It had to have a broad oblique nib. The only other cartridge filling pen I have is a Mont Blanc Bohème where the cartridges seem to quickly self-empty into the cap, on an airplane or not. Pity because it has a nice OB nib, which is more than I can say for its big "Le Grand Meisterstück" sister's OB nib. I was pleased when I got the G v F-C Classic pen. It looks to be very well made and writes beautifully, with nicely controlled ink flow, using Pelikan ink.
Disappointingly however, it has proved to be rather leaky. Now I know that we have had very hot weather in the south of France and even at 800m/2500 feet altitude, we have seen 38ºC. It seems to be leaking from both the nib into the cap and around the filler unit, into the back cover. I am reluctant to return it, as I suspect it will come back exactly the same and this is a characteristic of its design rather than any fault. I will buy some G v F-C ink, to make sure it is not the fault of the Pelikan ink being too low viscosity but I very much doubt if it will make any difference.
it shows that I suspect it will be essential to wash out the pen before air travel and take cartridges with me. From some other comments, I had hoped otherwise. I looked at some other pens with ink shut off but was not enamoured of the nibs.
