Organic Studios Elements Fountain Pen Ink, 55ml, Nitrogen Royal Blue

Have really grown to love this ink. Flows nicely and once it is dry has a lovely colorful sheen. Excellent ink.

I've read some horror stories about this ink, however, I have an experienced any of those myself. I put this in a Twsbi diamond 580 ALR, medium nib; never had a problem with it. It doesn't dry out in my nib has respectable sheening of a deep blue with echoes of red, very wet ink flows well in my Twsbi overall very happy and will probably buy more organic studio inks .

This was written with a TWSBI Go stub nib; you probably can't tell in the photo the beauty of this ink!It flows smooth in every pen I have tried. I can write on the cheapest of papers with this ink if I have it in my TWSBI GO Extra Fine! I'm thrilled!! That sheen of another shade/color is the best!It doesn't dry super fast, but it's worth the wait!

Organics Studios creates stunning inks, and Nitrogen is no exception. It's sheen tasteful and very strong.I have included both an image of typical writing using an extra fine nib, and with a very wet pen. Ignoring my ugly writing, it's clear that the sheen is very powerful, and it can show up on very small nib sizes. It's also spectacular on wetter pens.In the second image, I show the variation this ink can provide, side by side. The sheen is visible in both.In conclusion, this ink is one that everyone who has a fountain pen should have. It's great for gifts for that writer in your life. I would strongly recommend

Have been on the fence about this ink as extra fine and fine nibs are what I use. But I finally broke down and bought this marvelous ink. It is a wet ink so it works well in my pens. The color and sheen are amazing. The red sheen is awesome. When I was in grade school the ink in the ball point pens had something of a sheen like this ink. This ink is now on my list of inks to never be caught without. This ink is such a pleasure to write with.

Great ink, sheens really good on most paper, arrived a lil messy but bottle was still pretty much full so idk what happened there, I cleaned it up and it works great so no complaints here.

This is a great ink - it has a tremendous purple sheen that's quite attractive. My only word of warning is that it's a volatile ink - it will dry enough on the nib to hard-start the next time you put it to paper with only ten or twenty seconds of disuse. When writing passages with it, this is not a problem at all and it flows generously, but if you're using it for note-taking, you have to remember to re-cap the pen constantly whenever you're not actively writing.

Like I said in my title, this ink is gorgeous. It's a deep cobalt blue with reddish, pinkish sheen. I filled my TWSBI Vac 700R with it and it glides onto the paper. I can even see the sheen on regular printer paper, which is important to me since I don't usually print on nicer paper. It doesn't bleed or feather and is my go-to ink right now. I honestly will probably never use it up, but if I do, I'll buy another bottle if it's available.
