It seems like good value I will treat myself later but with a converter.I would appreciate recommendations on a good ink
@Ferrum that is water resistant but not iron based. I used to use a Cross fountain pen but their ink (in cartridges) was nowhere near to the same standard as the pen. I have been using Uniball gel impact pens recently because though the pen is cheap plastic, their tamper proof archival ink is terrific. I keep journals and I know if i accidentally knock over a glass of water the work will not be ruined.
Waterproof ink is a tricky topic. I personally use it only with a dip pen, as most of my notes aren't too important, and I tend to protect any that are from getting wet. I use Indian ink and have used Rapidograph ink, but wrecked a couple of Rapidograph points with the latter, through dry-out.
I've heard good things about Platinum Carbon Ink, which isn't apparently an iron-gall ink, but still needs plenty of throughput and attention to cleaning. The other ink you might wish to look at is KWZ iron gall ink. It is produced in colours, some of which have a low gall content, and one is reckoned to be close to ordinary ink. Again, there are many caveats on frequency of use and pen hygiene etc. KWZ is a one-man handmade ink operation, in Poland -

I think the only UK source for KWZ is Bureau Direct : -

I use the normal KWZ ink, and it's great stuff.
Perhaps it's a bit theoretical, but, based on past experience with "fast" (as in lightfast/waterproof) inks, I think that a broad nib with plenty of wetness is essential. When I have tried such inks, either in fountain pens or in dip pens, thin nibs never seem to give good results, but plenty of problems.
The good thing with these pens, when used with a converter, is that the whole guts of the things can be got out quickly for soaking and cleaning. The screw-in nib and feed unit (in my case Schmidt) can be just unscrewed, unlike the push-in units with separate nib and feed; and the converter can of course be pulled off and soaked. By the way, Schmidt also do reasonably-priced converters. See
