Bottle Ink iroshizuku Shinkai, Blue, 50 milliliters

Beautiful blue ink color. Looks professional. Like every single other Pilot Pen Co. product I have ever used, this ink is outstanding in quality and performance. The ink color is pleasing to the eye and it flows smoothly. I have only used it in my Pilot Pen Co. fountain pens with both fine and medium point nibs and the writing experience is very enjoyable and satisfying. No smudges or blotches or smears. The ink dries quickly and seems to work well with all types of paper regardless of the paper quality - so far. This is a superior ink product and I like it so much that it may be the only color I use from this point forward.

Very good quality/color ink. I would buy from this seller again.

Nobody ever mentions this but this ink comes out bright blue and darkens into blue-black when it dries. This makes it one of my all time favorite inks and the only bottle out of many, many bottles that I will soon run out of and have to repurchase. You can't go wrong with this ink. Pretty, yet professional, runs flawlessly in any pen I have used. If your pen doesn't run great with this ink, you know your pen has an issue.

Simple but nice color, smooth out of the nib.

This item arrived intact. The lid was intact, no leaks or broken seal.

I have a Pelikan ‘1935’ limited edition pen in lapis blue that long has been neglected because I never liked writing with it; it has been a dry and slightly scratchy writer. Having heard these iroshizuku inks are as free flowing as you can find, I decided to try the shin-kai blue/grey version. The pros: For starters, the presentation. The bottle is heavy, nicely proportioned and beautiful. In my ‘1935,’ the ink does indeed flow freely. It seems to be well-lubricated as well; and after just a tiny bit of abrasive smoothing, the nib and pen have become a pleasure to use. The cons: I’m not thrilled with the appearance of the ink. It’s a flat, rather washed out bluish grey — elegant, yes, but a bit too restrained for my taste. I often use Montblanc ultramarine and Pelikan 4001 royal blue, both of which are a lot more vibrant, but not in your face. iroshizuku is premium priced, as is the Montblanc ink; Pelikan’s 4001 inks are far more reasonably priced. For the premium price, I’d expect to be wowed by the look of the ink… this doesn’t do it. On balance, this ink does serve its intended purpose… it’s definitely free flowing and lays down a nice smooth line, without being unduly wet. Not up there with my favorites, but a good work around for problem pens.

Easy transaction, fast shipping & a great price. And Shin-Kai is even better than expected. The perfect blue/black for any situation. Great shading even with a Pilot Vanishing Point EF nib.

This is a fantastic blue-black, in one of the most crowded fields out there for an ink color. It's the kind of blue black that's on the navy end of the spectrum, and that deeper foray into blue gives it something that many blue black inks don't have: A subtle red sheen, particularly on Tomoe River paper, but it also shows up on Rhodia and Clairefontaine with the right nib/pen combinations. So Shin-Kai has the always-classy and sober blue black, but with a ton more pizazz and personality than any other blue black. Only Edelstein Tanzanite remotely comes close to matching this blue-black's wow factor. It's Iroshizuku, so it's also incredibly well-behaved in any pen you use it in. This is the blue-black for you if you need to be professional, but still want to stand out. Cannot recommend it highly enough.

Sehr sehr schöne Farbe. Der Tintenfluss ist sehr gut.

色は深い青緑（ネイビーブルー寄りのシアン）で、落ち着いた“深海”の名にふさわしい色合い。濃淡が出やすく、筆圧やペン先で表情が変わります。

Colour is subjective. The colour is very close to Lamy blue black but more lubricated. The ink is lubricated and that making all pens writing smoothly. The colour is also similar to Platinum blue black but this one is more water resistant but not waterproof. On most paper, with a wet pen writes blue but turns dark gray once dried. On some paper with a not so wet pen, it retains the bluish tint. It is a very good office ink that I can use for journals as well. Except the cost, everything else is what a very good ink is supposed to be.

Tinta azul estupenda, altamente recomendable, húmeda y suave. Intenso azul con tonalidades según sea la presión.

You can never go wrong with Pilot. Love the color, its smooth to write with and the bottle/packaging are very high quality
