I’ve finally got the new, extra-fine nib for my old-style Rotring 600 fountain pen. Seems to be flowing well, although changing nibs was a tough operation and required a bit of experiment. It wasn’t flowing properly at first and I found I had to push it in an extra milimetre to get it going consistently. Now it writes first time. Which of course it is supposed to.
Now I just have to get used to how thin the line it creates is compared to the medium point Parker pen I was using.
In case you need fountain pen advice, here’s plenty.
