My thanks to Ana of Well Appointed Desk for the ink sample.
Nitrogen blue is a sheening ink. But that’s not a surprise for any one now. I’m pretty late to this bandwagon after all. It’s a dark blue ink that’s super saturated and lubricated. It shades well and has a strong red sheen. You don’t even have to have a ton of ink on the paper to see the sheen to show up. It’s even sheening on my nib collar and grip. That’s how much it shows. It also dries up quickly on the nib if you take too long to figure out what to write next. If you’re looking for a super sheening ink, this is the one for you.
Though I have to say, cleaning is a pain the ass, because of how saturated the ink is.
