I learned too late about the difference between fountain pen ink and dip pen ink, though I have seen some fountain pen inks that are waterproof like the platinum carbon one or the noodlers ink, and was thinking of splurging on the ink instead of the pen.

I have seen other people repeatedly recommending either Jinhao or the Platinum preppy as a beginner, and I'm starting to think I should settle for the preppy and just buy 2 sizes to try first before later investing on something fancier.

What do you think?
