Pilot Iroshizuku Tsuki-yo - Moonlight (50ml Bottled Ink) is rated 4.7468 out of 5 by 79.
Rated 5 out of 5 by from Breathtakingly Beautiful For years, I have used S.T. Dupont?s Blue Black (encre nuit) ink in my collection of S.T. Dupont pens. Much to my dismay, S.T. Dupont has discontinued the ink, however, so I embarked on a mission to find a replacement, which resulted in my discovery of Pilot Iroshizuku inks. The Iroshizuku inks perform exceptionally well in S.T. Dupont pens. I love Tsuki-yo, which performs remarkably well in S.T. Dupont medium and broad nibs, due in part because it shades so well. Tsuki-yo is now my standard ink for S.T. Dupont medium and broad nibs. Although Iroshizuku inks are expensive, S.T. Dupont inks are even more expensive, so now I am glad that my former favorite ink was discontinued. This ink is superior in every way.

Rated 5 out of 5 by from makes like blue ink I am one of the weird ones that just doesn't like blue or black ink. This moody, smoky, dark teal just is much more than a blue. It has a nice variety of tones and on nearly all the paper I've used it on has been effortless. It does take a moment longer to dry on the coated Leuctteurm paper, but nothing that interferes with my easily derailed train of thought. Using this in a std. int'l cartridge (filled with a syringe) in my new medium point Kaweco Ice Sport (in pink). Lovely smooth stuff. Haven't liked a blue this much, ever.

Rated 5 out of 5 by from Treat yourself If you are reading this then you have an interest in ink at some level. Seriously, treat yourself to at least one bottle of this ink. There couldn't be one review here that doesn't tell you how beautiful this ink is. I will add that the bottle is beautiful and the ink looks beautiful in the bottle. I have it displayed on my book shelf. It's gorgeous. I use this ink in a beloved pen at work. Typically when I am starting to feel stressed or overwhelmed, I take out a note book with wonderful paper and start prioritizing. That makes it better. Treat yourself. A wonderful pen (it doesn't have to be expensive to be wonderful - check out some of Brian's videos) a nice notebook and this ink. Personally, great return on investment.

Rated 5 out of 5 by from A new favorite INK! I have never been a blue ink person, but this ink turned my mind around. The richness and saturation of this ink just makes me melt. The wet flow from my beloved Pelikans is incomparable, yet it still offers up subtle shading for those who enjoy such inks. I can't recommend the Iroshizuku line of inks highly enough! Each one I have used brings a new joy to writing I had never had before. (I've been a fountain pen user since 1965.) Not only do these inks have great colors, and wet flow, but the colors are, to me, unique. Well worth the price in my book.

Rated 4 out of 5 by from Interesting Blue/Green I just received a sample of this ink and filled my TWSBI 530 with it. Like so many of Iroshizuku's inks, I'm on the fence with this. From a quality and performance standpoint, this ink lives up to Iroshizuku's reputation for being silky smooth with excellent flow and lubrication properties and from that perspective, this ink is top notch. From a color perspective, I'm just not sold on it. I prefer highly saturated inks and have yet to find an Iroshizuku ink that's dark and saturated enough for my taste. This ink is a dark blue/green or teal color matching the sample swab above almost exactly. It also shades very well, starting out as a very light almost sky blue and fading to a dark ocean blue. I'd highly recommend this ink to fans of those with shading properties. Overall, this is an excellent ink, especially from a performance and shading aspect, but for my personal use, it's not dark or saturated enough.

Rated 4 out of 5 by from Good Ink I love Iroshizuku inks, Kon Peki being my favorite. Tsuki-yo is another great ink. Awesome shading, even in a fine nib. I wouldn't call it a blue-black ink, but it's still a good color. More of a cross between a slate blue and a turquoise. It behaves well on most papers, including office supply legal pads. Dry time is fairly quick and the color is suitable for business and correspondence uses, Tsuki yo will be in my regular rotation for sure.

Rated 4 out of 5 by from Magic on paper :) Tsuki-yo has a truly amazing color. I've tried it with various dip nibs and with my namiki falcon fine semi-flex... It turned out to be unexpectedly saturated with beautiful shades and I would say rather wet ink. I noticed some deep reds here and there. On rhodia and moleskine paper it bleeds and produces feathering (the worst behavior was on rhodia). No problems on clairefontaine or g. lalo and some other cheap paper.

Rated 5 out of 5 by from Amazing, deep blue. (Almost blue/black, almost). This blue is a real "Moonlight blue." It is definitely all about 'the blue,' yet it has a shadow. It is NOT blue/black, yet it could pass as such because of its darkness. I find it to be a stellar everyday blue. The "Iroshizuku" line is superior. I HATE the price (see below - not Goulet's fault), and normally knock it down one star because of the price, but this color/ink is unsurpassed. It is AMAZING in all my flex, wet-noodle, and semi-flex pens! It has great variety in its depth of dark blue. It is my favorite blue ink to use when writing cards or personal notes in calligraphy. It flows great, and writes fast. PRICE: The "Iroshizuku" line is superior (flow, consistency, color saturation,...). I HATE the price, but that's something Pilot needs to sort out (Goulet's price is great). If Pilot made iroshizuku more affordable it would be the only brand of ink I use.
