Ink Review: Sailor Kiwa-Guro Carbon Nano Black


Kiwa-Guro Black is one of Sailor’s “luxury” inks, more costly than their standard Jentle line. This is one of Sailor’s two pigmented inks, made with ‘nanoparticles’ – they also make a blue-black called Sei-Boku.


I finally got a picture of the inner cone of Sailor ink bottles. I took the cap out of the bottle and put it on the lid for a picture. You tip the bottle upside down, and the ink goes through the two holes at the top, and sit in the cone when you turn the bottle back upright.

Pigmented inks are different from dye-based inks (most other fountain pen inks) in that they are made with micro-fine pigments suspended in the liquid to give the ink its colour. In order to make these safe for fountain pens – to prevent persistent clogging or flow issues – these particles are really micro-fine, and the inks are designed for fountain pen use.

Be careful not to mix these up with the inks that are not okay for fountain pens – India ink, calligraphy ink (thicker, to hold a little better to dip pens) or inks that have shellac in them. These inks will definitely clog up your fountain pen’s feed, and may even cause more permanent damage.

The writing sample was done with Noodler’s Nib Creaper Flex fountain pen.


This ink, because it’s a pigment ink, offers a really rich, deep black colour. It’s not the blackest black you will get (I think some consider Noodler’s Black the blackest you can get), but it is one of the deepest blacks you can get. It’s a dense black, with no shading at all, even with a flex pen. On the Rhodia, there’s no feathering or bleeding, but it’s generally a pretty good ink. This is definitely a crisp, dark, clean line.

This ink is definitely smooth. Sailor’s inks are generally very smooth, and this ink is no exception – it glides across the page.

This ink behaves very well, and while I have read reviews that found it long to dry, I found it to be not bad at all in dry time. It’s a sophisticated black ink for the office, but it’s fairly waterproof as well. However, one of the things I love most about this ink is that it’s kind of got this balance between being super matte when you look at it head on and having just a hint of sheen when you look from an angle.


A hint of sheen!


You shouldn’t have any clogging issues if you have generally good pen habits. This is not an ink you want to leave to dry out in your pen – not that you’d want to leave any ink to dry out in your pen.

I would suggest that you at least scribble a bit with your pen to get things flowing every other day or so to be on the safe side. Even when using this ink again on a refill, you may want to clean out your pen between each filling (rather than just refilling directly) just to get any particles moving out.

It is more expensive than the inks in the Jentle line, but in my opinion (as a retailer!) it’s worth it – it’s a rich, smooth, dark black. You can find it here.

Sailor Jentle Black Ink Review



Sailor Jentle Black is a dark, rich, warm black.

Sailor is one of my favourite ink brands, and while some of their inks are known in particular
for beautiful shading and a sheen, the Jentle Black is a great ink for your everyday writing.

The review was done on Rhodia 80gsm paper, with an eyedropper Serwex 101 with a flex nib – one of my favourite no-nonsense get-er-done pens.

One of the most distinctive features of this ink, but also most of the inks in Sailor’s Jentle line is the lubrication – it’s super smooth and wet and flows beautifully.  It’s a great ink to try if you have a drier pen or in flex pens.

I love the sheen from some of Sailor’s other inks, but this is not an ink that will give you too much shine when it dries. If you’re looking really close at the right angle you might see the tiniest hint of sheen, but it might also be because you’re squinting too hard.


Even with the super wet flow and a flex nib, on the Rhodia paper, I got zero feathering or bleed-through. The flip side of some inks with low or no feathering is a long dry time, and this ink is no exception. In part because it flows so well, and lays down such a nice wet line (that doesn’t dry in feathering) is that it will take a little longer to dry.

It’s a dark, opaque black, with just a hint of shading. There might be other blacker/blackest-possible inks out there if that’s what you’re really looking for, but this is a warm, dark, rich black.


Just a few flecks of sheen in the right light.


Sailor Jentle Ink Bottle – a wide base to prevent tipping. Each bottle has 50mL.

Typical of Japanese design and innovation, the bottle is one of the most user-friendly ink bottles on the market. It’s a bit hard to tell in the photo I took, but there’s actually a cone inside the bottle that allows you to draw from the bottle even when you’re near the end. With the lid firmly closed, you turn the bottle upside down, and back upright, and ink will have filled the inner cone, allowing you to fill up.


The Sailor ink bottles all come with a cone to help you use the last bit of your ink.

The Beginning of the Beginning

…of what we hope is a long and exciting journey.

The first of our shipments have begun arriving! We have currently placed orders or begun discussions with several companies, and the first three have arrived. It’s been a learning curve with UPS and getting through customs with brokerage fees and duties.

We are putting Private Reserve ink (US), Sailor fountain pens and ink (Japan) and Rohrer & Klingner ink (Germany) up on the site now. While you can’t actually buy anything yet – we haven’t quite launched the site live – you will be able to on April 17th. We’ve set this date in anticipation of the some of the other products we hope to have soon, but some of our orders are coming from pretty far so they might not be up on the site by launch.


The following ink colours are available in Private Reserve, all in 50mL glass bottles except the Invincible Black:


Gray Flannel
Shoreline Gold
Rose Rage
Ebony Purple
Fiesta Red
Naples Blue
Midnight Blues
Spearmint Green
Ultra Black-Fast Dry

Invincible Black (60mL)


The following colours are available in Rohrer and Klingner inks, available in 50mL glass bottles:


Blau Permanent
Leipsician Black

Iron-Gall Scabiosa
Iron-Gall Salix

And as well, we’re carrying three colours in the traditional drawing ink – not meant for fountain pens – for technical drawing, calligraphy or dip pens. They come in beautiful, large glass bottles and are available in: paynesgrau, bordeaux and ceresschwarz. 


We are also carrying Sailor products.


In fountain pens, we have the Reglus, Professional Gear Slim and Professional Gear in black, grey and orange. We don’t have nib sizes available for all pens, but we do have at least one of each of their seven nibs sizes available.

In Sailor inks we have available in 50mL glass bottles:


and the two:

Carbon Nano Black (also available in cartridge)
Carbon Nano Blue-Black (also available in cartridge)


We are expecting to get some paper and a few other fountain pen brands in soon from Germany, Japan, the US, China and India.
