Great color

For reference, I used this ink in a Lamy All-Star with a Fine nib. It ran very smoothly if a little wet. But no bleed-through and just the slightest bit of feathering. This on Rhodia and Tomoe paper. I absolutely loved the almost black tone with the green highlights. I have other samples to try but will certainly get more of this one!

This is an extremely dark forest green - looks nearly black coming out of a fine nib. The shading is not extreme, but when you see it, it's obvious where the name came from. It has an extremely - well - velvety look. It's not a loud color, but it's more interesting than your standard dark green or black. I've been in sample all the things mode recently, but once I settle down, I plan to keep this in the rotation for my everyday writers.

Wet DARK green

This is a DARK forest green. I'd almost call it more of a black that leans green. The velvet in the name is apt - it dries with a very smooth texture that is very velvety. The ink is very wet in my TWSBI Go with a Fine nib. Slow to dry, but once it dries, it's hard to smudge. The most notable thing is that while the preview image shows a sheen, I am getting NO sheen whatsoever with it.

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.
