Buy this!! This is a fun ink and so far is very smooth , no clogging and leaves me inspired with every stroke! 🥰

The sheen is as many and obvious as everyone says and how easy it smears is also as bad as its reputation. The color is more vivid than the picture, which makes it less elegant but more eye-chaching. Overall, I wanted an elegant purple blue ink so I am not a super fan for this one, but it's good for someone who likes the ink stand out. I used it on Tomoe river in a Monblanc EF nib.

Nice ink, great sheen. Tested with Kaweco Sport, Optik PaperGood flow, medium wet, quick dry time. No skipping or hard starts. Has a dark almost navy blue tone when its wet but dries to a lighter, royal blue with a nice red sheen. Not my first choice, I prefer very wet inks but I can write on copy paper with this in certain pens. It reminds me of rollerball ink on glossy paper.

Sample size of the ink was not enough for my fountain pen. The color was just okay. It wasn’t what I expected.

Nitrogen! One of the gifts for my grandson’s birthday. I’m sure he’ll have fun with the sample.

Looking forward to purchasing a whole bottle.

Gorgeous sheen!

Very nice blue colour

This ink would work best with fatter nibs. The thin line produced by a fine nib does not allow the color shift to show up as well or as often.

It’s ok.

There is a reason that this is the most popular color. Love it

Helpful hint. Don't bother with a sample. Go straight to the bottle with this one!
Stunning

GORGEOUS! I'm gonna have to get the full size. I love this ink.

This ink is so fascinating, like many others, I was taken by the interesting properties of this ink. Will be getting the full bottle of this in the future!

Goulet pens always package items with such care and have excellent customer service.

I used this ink in a fairly wet nib on "regular" paper and got next to ZERO shading. I did, however, love the royal blue color on its own. After an email to support at Goulet, I tried it on a higher quality paper and got the reddish shading that I saw in swatches. I'm now deciding whether to buy a bottle of this to use on lower quality (higher absorbency) paper or to use it in my higher quality notebooks.

Beautiful color to it!

In terms of how nice the ink is, it's incredible. It's beautiful. But by god do I hate the bottle. This ink likes to sputter and spit, it always forms a bubble film that flicks highly dense dyes on your work surface and god forbid your paper (It hit the side of my journal, on the side where the pages are). It's filled nearly to the brim, and it's plastic which means accidentally squeezing when opening or opening on a not perfectly leveled surface is a surefire way to make a mess. It gets in the threads and inks up your fingers when trying to open or close the bottle. It gets EVERYWHERE. I've resorted to only using gloves, and only on easy to clean surfaces when handling this ink.Will buy another bottle. And probably Walden.

This is a very vibrant and beautiful ink, with clear sheening that shows up beautifully. However, even on regular paper this can take a very long time to dry, and it also has very low water resistance. It is a more difficult/advanced ink to use, but it brings great results.

gorgeous sheen. bought it for a friend who loves things like this and he purchased a whole bottle within a day! I am not as enamored with this ink as he was though. it gets stuck in my nib alot and I lick it to get it flowing again (it doesn't have much of a taste) and thankfully it's not very waterproof so it's a little easy to get out of my pen. it smudges alot though. ughhh but it's so pretty.

Lots of sheen. Messy ink and kinda of got everywhere.

This is my first Organics Studio ink purchase and I can confidently say I'll be purchasing the full size. I've never tried sheening inks before this one but I've found that it offers just a little extra magic to my notes and journal entries.

Really interesting results, the light really does affect what color you see on the page.

My first sheening ink was Nitrogen, and like other first loves, it still strikes me forever beautiful, full of charm and nuance. Modest rotation or gentle shaking of the pen is all it takes to bring out the best sheen and prevent any clogging. I use it in a flex pen, so my line varies from fine to broad, and as it dries (quickly enough), with a tilt of the page, the rich blue reveals its soul to be a beguiling reddish-purple. Irresistible!

Mesmerizing ink color.

This ink has definitely made a name for itself in the community and for good reason. It flows well and wet, then takes a bit longer than most to dry, and once dry it is a small rainbow of color going from the base blue to a deep purple and finally to the red sheen. I used it with a 1.5 mm nib and I think that was the perfect combination of flowing script and the color change properties.

This is a great ink! I used it in a .7 mm stub nib and the result was beautiful

Writes smooth in pilot metropolitan and lamy safari and is pretty

This ink is pure fun for writing with and reading what you've just written! However, as other people have said, it dries in the pen very quickly. I used this in a Pelikan Twist. I wrote with it right away, capped the pen while I had to walk away for a bit, and when I came back maybe twenty minutes later, the pen would not write immediately. I would not use it in any of my vintage pens.
