Iroshizuku Bottled Fountain Pen Ink, Ku-Jaku, Peacock (Turquoise) 50ml Bottle (69213)

The colour of this -- dark turquoise or peacock blue, depending on how you want to translate it -- is exquisite, first of all. A deep, saturated ink that isn't so flashy that it can't be used in a professional setting. It writes well, getting a touch lighter when the pen needs a refill, and it doesn't smear, feather, or bleed. This is my first bottle of Pilot ink, and it certainly won't be my last. The bottle itself is a lovely thing and it sits with my pen, since I write with a heavier hand (a bad habit) and need to refill my pen frequently. The elegance of the bottle makes that far from a hardship. The descriptions from Pilot are marvellously evocative, and the ink delivers on what they depict. A lovely, functional, good value ink.

ink quality is superb and the color a feast for the eye of course made in japan you can expect nothing less than perfect will buy again been using it since over 15 years

Gosh this is such a pretty color. My life is slowly devolving as I delve in to the world of fountain pens. So far I only own the Pilot Metropolitan (in fine) and the Lamy Safari (in extra fine) because I really only wanted to use the pens for drawing and they seemed suitable enough. I tried this ink (Ku-Jaku) in both pens, but I prefer it in the Safari because I can get thinner lines with it for my sketches. I also own Noodler's Bulletproof Black, but I could never seem to make it write smoothly at all with the Safari...even with cleanings and stuff. Other people have been able to, apparently, so maybe I just have a slightly faulty nib? Either way, I use the Bulletproof Black with my Metropolitan because it writes thicker and the Ku-Jaku with the Safari. I'm happy with that arrangement. I've only used it on notebook paper, printer paper, sketchbook paper (strathmore?), and watercolor paper. It doesn't dry all that quickly, and it does feather very slightly on some of the words/letters when using it on printer and notebook paper. It's not like they're high quality paper anyway, so I don't really mind. It probably helps that my Safari writes very thinly. I love how the ink looks more green in certain light, and more blue in others. That's my favorite ever. The bottle is beautiful too. I want to try more colors eventually, but with the price tag I wont be buying them all willy-nilly just to see what they look like. However, it's definitely worth getting if you're on the fence about trying one.

The ink arrived in perfect condition, in a nice silver box and secured in a plastic bag. I haven't tried it yet, but it looks to be a beautiful shade of blue. And you get a good amount of ink in a really nice, heavyweight bottle.

Love all the colors of the PILOT Iroshizuku Bottled Fountain Pen Inks! I started off with two colors and now, 3 months later, I’m on my eight! Each color is a standout; no two are very close to the other (which I find to be the case with many of the higher-end inks). They flow perfectly. I mostly use it with my Kakimori Brass nib dip pen. Flows like a dream!! 5-Stars…but I’d give the whole line 10 stars if I were permitted!

Someone below said this is a gateway drug. I completely agree. These inks are not all that expensive for the enjoyment you will derive. If you have a nice pen, you should have nice ink. Ku jaku (which they also call peacock) is a blue that doesn't look like everyman's ball point blue. This has a good dose of green in it, so it has a vintage appearance, like letters I've seen in official British correspondence from the 1930s. A really nice vintage look on paper, and although it is lighter in tone than a dark navy blue, this shade stands out on white paper. and is easily distringuished from black print. So I use it for editing and marking my associates' legal writing when I need to use a pen. I notice that this formulation migrates to the top of the nib and stands as a film unlike cheaper Lamy ink. Also, I had a converter filling mishap and also learned that this ink stains skin for about 24 hours. Harder to wash off than sharpie in my experience. Take care wtih filling.

Would have given it 5 stars but I was sent Syo-ro instead of Ku-jaku. That said, I’m actually really happy with the wrong color I got. A nice green/blue/teal color. All of the Iroshizuku inks are really wet and beautiful. No matter what color you get there’s always something to enjoy whether that’s the color itself or how well it flows in your pen. These are great inks.

Love it! Gorgeous color, smooth write. Very consistent high quality, as always!

Supero mis expectativas, un arte escribir con esta tinta.

What can I say about these inks, they are quite simply some of the best inks out there. I have had most of them over the years except black which is one ink i never use, I have the grey(Fuyu-Syogun)instead. They are used in cheap Jinhao pens up to Pelikans/Montblanc and suite all of them. Consistently smooth, wet and never let you down. Yes they are expensive but last ages so go treat yourself, you won't be disappointed.

Ink tends to dry in the nib unless used everyday. Excellent shade of Turquoise. Cost is a bit high !

The opened cover had ink leaked n broken cap completely. The sleeve also had stained completely.
