Namiki Iroshizuku Chiku-rin Bottle of Ink for Fountain Pen 5.000 blue-green

Just the finest inks in the most sumptuous of colours. The bottles last for an eternity so ignore the price and treat yourself. It is a joy to write with and will bring colour into your life.

I have to admit that my go to Blue Black at the moment is the extremely lovely Diamine BB, which is really effective through all my F and EF nibs. It's saturated, super lubricated and shades beautifully. I saw the Tsuki-Yo and had to buy it at the price offered here on Amazon by Santa in Japan, and I'm glad I did.Don't be misled by translation of 'Moonlight Turquoise' - it's not turquoise - Pilot Tsuki-yo is a beautiful blue black with a hint of turquoise that, through my fine nibbed pens has a lovely greyish green tint to it that is midway between the Diamine BB and a blue that leans towards turquoise slightly, (Diamines Majestic Blue being a case in point).I've just dipped five different fine nibbed pens, and (sad face) unlike my other Irishozuku inks, I can't get it to shade, but the upside is it hardly feathers even on the cheapest papers (T*sco squared notepad being the lightest I tried).And the more I look at it in natural light, the more it resembles Sailors Sei-Boku in colour - just a few shades darker, especially on cream paper, and that can't be a bad thing.It gives a nice crisp line to my script, and it's very satisfying to use, it dries quickly and shows no fading after 48 hours on the windowledge in bright sun.Although it performs well through fine nibs, I know Tsuki-Yo would be stunning through M and B nibs (especially a stub) as this the extra flow would really show this ink off at it's best. I have one B nibbed jinhao that I use purely for comparison purposes and Tsuki-Yo through that is a truly gorgeous blue black without any hint of grey/green, I wish my handwriting fitted fatter nibs, but hey ho.The bottle is beautiful also, with its trademark crystal glass and internal indentation for the nib, and I always smile at that silver grey cord...very classy.Am I pleased with this purchase? Absolutely, this is a nice addition to my collection and an ink that could be used for both personal or business use. Buy it with confidence, it really is that good.Hope this helped.

There are many good inks, some not so good and some that are superb.This is the latter.Firstly, the quality. As you creep up the fountain pen quality you start to see what a real writing instrument can do. That is not to say you have to have a great pen to appreciate this, no this ink performs well full stop. As you start using great quality pens however (and I don't mean expensive) you notice that ink can make a very noticeable difference to your handwriting.You wouldn't put supermarket fuel in a sports car, and you really shouldn't use poor quality ink in your pride and joy fountain pen. Well you can, but why would you?The flow of this ink is sublime, and this ensures a steady predictable flow as you write. You really can't get much higher quality and there would be no need; this ink will give superb results time and time again. Compatible as far as I am aware with all types of pen with all types of filling method.I could be wrong, but I have used this with Pilot, Pelikan, Parker, Lamy, Waterman, Conklin, Graf von Faber Castell, Scheaffer, Cross, Swan and even Mont Blanc (ew). Yes I dislike Mont Blanc intensely in all it's incarnations but that's a different story...This ink is the business.Colour wise, it is a wonderful deep shade that really stands out from the usual suspects (Waterman/Quink etc) and definitely has a premium look. I also really like the Bamboo Charcoal black in this range too, if you can find it. It can be a pig to get sometimes.I would give this 10 stars if I could, a great line with some superb colours. I also really like the Ina-ho Rice Ear too, for something quite unique.Enjoy!

The colour is fantastic

Other blue-black inks I've encountered (*cough*Parker*cough*) have had a very light blue colour on the paper after the ink is dry. This ink, however, dries to a very pleasing dark blue; nearly a navy blue on my Leuchtterm 1917 notebook's (ivory) pages.The ink's presentation in the bottle is fantastic and the idea of placing a nib-void in the bottom of the bottle means that you'll be able to get more ink out of the bottle into your pen without having to decant it.The ink dries reasonably quickly, but a splash from a water bottle post-dry will cause the ink to run rather badly. This is not a waterproof ink - nor does it claim to be.This ink does seem to write rather wet; shine-through is something of a problem for me with a Waterman Carène pen and medium nib in the Leuchtterm notebook; with the same ink and a Lamy 2000 fine nib, I observe less of a problem, but nevertheless still some amount of shine-through.With a slightly sturdier notebook paper, I would without question recommend this ink; it is absolutely the best blue-black colour I've tried bar none. As it is, I recommend it for the colour, but advise testing with the pen and paper combination that you're using that shine-through isn't an issue.
