Chou Kuro is the blackest ink ever created from Platinum in its 104-year history! An ink that is blacker than black, and 46.8% darker than Platinum's famous Carbon Black, this new permanent ink from Platinum is going to set the new standard of what is possible from permanent black ink in the fountain pen market. 

With the growing interest in fountain pen inks in recent years, the variation of ink colors is also increasing. In response to the customersʼ request for a blacker ink, Platinum Pen has developed a new ink that is the best black ink ever in its long history of 104 years since its founding. The new ink, whose blackness has been proven by numerical values, offers an excellent visibility with a clear and intense black color, allowing you to keep memories and records on paper. In addition, it prevents the ink bleeding through onto paper while also being highly water-resistant and fade-resistant after writing, making the ink ideal for writing letters, journals and anything else you want to last a lifetime. Enjoy the true black color like never before.

Caution: Pigmented inks are intended for use in fountain pens, though they require more diligent maintenance and should not be left to dry out in a pen. It is best to clean it from your pen at least once a week to prevent clogging. Certain pens may handle pigmented inks better than others.

Beautiful and well behaved

I bought this expensive ink while I was a little buzzed (mea culpa!). I woke up regretting it a little bit: did I need another black ink when I already had Platinum Carbon and Herbin Pearl Noir?!? Well, I certainly didn't need it, but I'm glad I have it. It's rich and dark and is a joy to write with. It's going to be the semi-permanent choice for my Pilot 912 . So, if you've got some money to burn, and you're half-drunk, go ahead and pull the trigger on this gorgeous ink.

It's black alright

It created a black hole. I lost my desk. But it is incredibly black.

The best black ink for drawing

If you want to use your fountain pen to draw with this is the ink for you. If you can not afford this ink then get the De Atramentis black document ink. It is almost as good. I have not used it in a line and wash drawing so I can not judge how well it will do with watercolors. The Chou Kuro is black from any angle, it dries fast and is water resistant. It performs well on regular office paper without bleeding or feathering. On Clairefontaine, bristol, and hot press watercolor paper it is a joy to use. It dries quickly but not immediately. The only negative is the price.

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.

You can learn more in our blog: How to Write with Shimmering Ink.

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
