Hey everyone,

I recently acquired my first fountain pen beyond the disposables (it's a Waterman), and have had fun using the ink cartridges. But they're just a little....lacking. So, I've decided to purchase a Waterman converter from Amazon and head into the wonderful world of bottled inks. I would like to hear your recommendations based on the following criteria I have:

• 1) A really nice deep blue or black (preference is blue; no sparkly or shiny inks please)
• 2) Something that is a reliable ink to use - I write a lot of essays and a lot of math
• 3) Something that doesn't smudge too easily (not too bothered about this unless it takes like five minutes to dry)
• 4) Something relatively inexpensive

Thanks!
