Nice high sheen, easy to clean

Nice high sheen, easy to clean

Pretty, but not for me

This is a nice ink. It sheens but not to the degree that I thought it would, and it takes a long (*long*) time to dry. That said, it is a striking deep blue, and if you're someone who writes with a broad or double broad nib on like, exclusively Tomoe River paper all the time, you'll probably love it. Glad I tried it but won't repurchase. It behaves fairly nicely in my medium nib Lamy Safari, although it is sometimes prone to hard starting.

Okay, so... this is my new favorite blue

This is jaw-dropping! The red sheen shows so nicely, even in a western fine! I can't stop writing with this ink - it would be a good alternative to OS Nitrogen and is very well behaved. Going to have to order a bottle soon!

The Diamine Polar Glow experience

Due to the wide range of color in this ink I installed it in my Duke Fude tip to give it the widest spread. Even at that width the color did not show much diversity. However when I re-wet the ink to introduce shading in artwork the resulting tones were profound. So far, every ink, pen, or product I have purchased from Goulet has shown to have the utmost care and consideration for the customer's pleasure. Diamine Polar Glow is no exception.

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.
