Perfect blue/black for me

This is a great color. Just the right amount of shimmer. It starts out as a very nice dark blue and then the shimmer hits it and it turns dark with coppery sheens.

Beautiful blue ink

I love this ink, truly like midnight. It has a hint to black to it. I'm a fan.

Great Ink!

Great InkI am loving this ink. When first used, it can almost appear to be black. It's only after drying, that the blue, along with a deep red sheen can be observed. Surprised that it shows the sheening even with 'fine' nibs. Diamine scored with this formula.

Wonderful ink

I'm quite fond of these special Diamine inks. This is a lovely deep blue with a beautiful obvious sheen, and I love writing with it.

Beautiful ink, gorgeous bottle

I LOVE this ink. I've been eyeing blue/black inks for awhile. I'm pretty sure that above all colors, it's my go-to, so I can get pretty picky, so I have purchased enough samples to have put off buying for awhile. When I saw this bottle, however, I snapped it up without even a sample. It doesn't disappoint as far as color, smoothness, worthwhile spend and again, that beautiful bottle. But one small thing which is a preference, depending on how you use it... It runs so badly with just the tiniest smidge of water. For notetaking with highlighters, I can't do it. And I was very very upset when my grocery list smeared all over my hands and became illegible when I visited the vegetable section (wet vegetables = list disaster). So I'll shop again for the water resistant ones for ease of use. I will remember to use this in my art sketches however!

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.

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!

What is your return policy for bottled ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B
