My New Favorite Ink

I've been a fan of Organics Studio Nitrogen for quite a while now, but Ruby Blues has come along and stolen my inky heart. Normally blue inks have been a meh unless they're something extraordinary (or turquoise but that's another story). Ruby Blues has that "wow" factor for me. While other reviews go into all sorts of details like whether it's wet or dry or what pen they use, I'm going to keep it simple and say this is a gorgeous blue shade with reddish/purple zing and makes writing by hand enjoyable.

Looking for a Good Blue

So far, the Regency Blue is ok. Not sure I'd buy a whole bottle. I'm looking for a hefty and attractive blue, and I keep hoping.

New favorite blue ink

I like darker blues. Midnight blue, blue black, etc. This is a rich and deep shade of blue but it seems to have a warmth to it as well. I dont know how else to describe it. It is really beautiful. I writes wet (like other diamine inks I've used)in both the medium and 1.1mm stub nibs that I've used it in. It's not the fastest drying ink either, but i am left handed and still love using it. Despite an occasional smear. The color is worth the bit of extra care that I have to use being a lefty.

Gorgeous Ink!

I just love this ink. The color is a dark, very saturated (I mean Noodler's type saturation) but still clearly blue versus blue-black. To me it has a nice sheen with a slight reddish tone with a Goulet 1.1mm nib. I tried to immediately order a bottle but most US sites were already sold out, I liked it so much I ended up ordering from overseas.

Great sheen

Really liked this ink. Will purchase a full bottle soon.

FAQ about Ink Samples

How do I fill my fountain pen from an ink sample vial? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It depends on the fountain pen's filling mechanism.

Check out our blog post on How to Fill a Fountain Pen from an Ink Sample Vial.

How much writing can I do with 2ml of ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It really depends on how big or small you write, and the nib size you’re using. We find that usually you can get 2 good fills for a typical converter with our Ink samples, or one good fill with a piston-filling pen. How much writing depends on you more than anything else, so we recommend experimenting with different nib sizes to find what works best for you. 

What is shading, sheening, or shimmering ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Shading - A common (and often desired) result of a fountain pen ink pooling in certain parts of a letter when writing, so that the color and saturation of the ink appears different within a single letter or word. This characteristic cannot be achieved with ballpoint or rollerball pens and is a very appealing aspect of fountain pen use for those particularly drawn to all the pretty ink colors.

Sheen - Characteristic of a fountain pen ink where when ink pools another color can be seen on top of the ink, especially when looked at in different light angles using certain paper types. There is no way to guarantee an ink will sheen, but using a larger nib on a pen will help obtain sheening results in your writing.

Shimmering - Fountain pen ink that has small particles of glitter mixed in.

Is shimmering ink safe to use in fountain pens? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Yes! Shimmering ink is a great way to add some flare to your writing. We have found that a larger nib will showcase more shimmering particles while writing, but you can use any nib size and shimmering ink. All the ink we sell is safe for use in fountain pens.

You can learn more in our blog: How to Write with Shimmering Ink.
