Denim true

This color matches its name, I like it a lot, dark blue yet different. Dries fairly quick.

My Go To Ink

I originally started using Diamine Inks after reading the chemical analysis of several prominent inks and finding that Diamine had absolutely no flaws as to Ph or clogging etc. I write most often with a Parker 75 extra fine cursive italic nib or a Pelikan tortoise shell and white 400 with an extra fine italic nib. I own other CS, Aurora, and Waterman pens but these two are my normal pens. I use my pens all day at work, and needed an acceptable color legally and professionally that offered some fun to my writing. Denim gives me some shading and shadoing, shows up as a blue-ish black on scans, and writes well while looking professional. Some inks in the blue-black range look way too black after drying. It performs well in these pens while drying acceptably quickly. I have no trouble writing on copy paper, or any modern crappy office quality paper except Post-Its. Fountain hate that paper for some reason. I like this ink very much.

Great Blue Black ink!

Love the ink! Denim is the blue-black I have been searching for. For work(accounting) it is a tad too dark, but I will definitely bee using it for journalism and personal use.

One of The Best

I've recently returned to the world of writing with a fountain pen (Yard o Led Viceroy Grand Barley - Silver in M nib). I wanted a blue that reflected my personal taste in ink as well as the character of my personal daily routine. I gave the Diamond Denim a try and was not at all disappointed. Smooth wet flow complimented the pen; when dried, provided the exact hue I wanted.

Diamine Denim (80ml)

Service was very prompt, packaging was good. I'm please with the color too. Softer than some of the bolder shades of blue.

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!
