Lovely ink

In my TWSBI eco this ink is much darker than the sample on the website shows, but I actually love that about it. It's a bit wet, so maybe that's why, but I'm quite fond of it.

Lovely color

Ink is a really dark, almost, not quite black, color, very saturated. Just a hint of purple in the ink shows best, of course, in broader nibs, but even in extra fine nibs, the color is more interesting than plain black, quite suitable for professional use. It doesn't feather, but does have some show through on even better paper. Good flow, fairly wet, well behaved. An interesting color (I like it!), but if you're really looking for purple, this is probably not it.

Dark yet subtle

I started with a sample, but after the first sentence written with a 1.1mm JoWo stub nib, I knew I'd be purchasing a full bottle. At first glance, it's almost black, but a second look reveals there's more going on: it's a deep violet, occasionally showing ever-so-slight hints of red or pink peeking through that deep, dark color. Such an interesting ink! I love it!Like all of the Robert Oster inks I've tried, it flows well and writes smoothly. It lays down fairly wet, but dries reasonably quickly. It is a bit prone to smudging and smearing, though, if you come back to it later with moist hands. Not an issue for letter writing, but I have to be a bit careful when updating pages in my day-to-day notebook. I'm totally sold on this one. It'll be in regular rotation.

Not purple.

The robert oster picture is a dark purple. This ink is not purple. This ink is black or a black-gray. I thought I had a bad batch, but after searching other reviews I saw that others also experienced that it isn't the color as shown. I feel bamboozled.

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.
