Incredibly Underrated Ink

This is one of my favorite inks, and not just because it came with my first fountain pen, which was a Platinum Prefounte. I really think this is an incredibly underrated ink as popular inks go, and really holds its own among them. It's definitely more blue than blue-black, and what a blue it is. It's hard to describe, sort of a hazy sky blue, it makes me think of a summer day. The shading is beautiful, and with enough on the paper it almost gets a sort of reddish sheen. It dries fast, flows well, and is quite permanent to boot. Do yourself a favor and add this to your collection

First converter

I have never used anything but cartridges before, but I got a converter for my Platinum Prefounte (which is a nice, inexpensive pen) and used this ink. I have used black for years, but I really like the blue-black. It looks like writing I have seen from the 1930s or something.

Ink is definitely doing what I asked of it

I am using this ink in a medium Kak�no to do crosswords. They are printed on what amounts to newsprint. Even on this paper I get no feathering visible to the unaided eye, no bleedthrough, and only the faintest hint of ghosting. On better paper it is unbeaten.

My favorite blue black and EDC ink

This is a sleeper ink for me. You don't see it around as much, and you don't hear about it as much as some of the other inks, but after trying it, this is perhaps my new favorite ink. Yes, it checks the box of business capable while not being boring, and permanent without being excessively high maintenance, as well as being well-behaved. But that's just the beginning. I didn't realize that I wanted this ink so badly in my life until I started trying out a blue, black, and blue-black ink from Pilot. I realized that black was the most legible, but also the least inspiring to write with, the blue was the absolute best to write with, and the most inspiring, but way to bright to read on a regular basis. The blue black from Pilot, unfortunately, wasn't nearly fun enough to write with and sort of felt depressing during the writing, even though the color itself was fine. But the Platinum Blue Black is more traditional, and starts of very blue and relatively bright. This makes it fun and exciting to write with. But it quickly begins to darken and as it does, the readability and legibility improve as well, so that you don't strain your eyes as much when reading what you wrote. This two phase ink coloring really makes a difference for me, and I can't believe how much more I enjoy writing with this ink relative to other stuff. The bottle is also well designed, easy to fill from, and practical. The ink itself is just really well executed, and when combined with the typical quality of Platinum's nibs and feed design, it's a wonderful experience. With my Platinum Music nib, I love the bold color, shading, and the two color effect. I get the legibility of a darker ink, with the vibrant joy of writing of a brighter blue ink. This is just an underrated ink and deserves more attention than it gets. The secret is not in its color, but in its color shifting, combined with permanence, ease of use, and beautiful shades of blue. I feel like I get a little bit of everything without having to give up too much, as I do with some other inks.


I think this is a really underrated ink. It performs so well on cheap notebook paper. No bleed or feather and it's waterproof.

FAQs about Bottled Ink

Which pens can accept this ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Any of these fountain pens will work with bottled ink. Typically, as long as the pen can be filled with a converter, has a built-in filling mechanism like a piston, or can be eyedropper-filled, it can accept bottled ink.

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.

My ink smells funny, is it safe to use? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Generally yes! Ink does not smell good- it usually has a chemical smell, along with other scents such as sulfur, rubber, chemicals or even paint. However, as long as you’re not seeing anything floating in the ink, it should be safe to use.

It’s cold and my ink froze; is it safe to use? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Yes, frozen ink will not hurt your pen (after it’s thawed of course!) The issue with ink freezing is primarily a concern because certain glass bottles could break as the water-based ink expands, and then you’d have a mess!
