Ink Shoot-Out : Pelikan Edelstein Aquamarine Vs Pilot Iroshizuku Ku-Jaku

Good review. I love the way bottled ink looks, but I'm a messy writer so I won't usually crack a bottle open on my own.

 

 

 

I'm surprised that the Edelstein ink has better water resistance. I once spilled Kujaku on my fingers, and it took more than a week of soaking and scrubbing to get the last trace off of my thumb!

 

 

I would expect the same thing! I really don't like inky fingers, and I once had an iroshizuku ink under my fingernail for four days after trying a friend's newly filled pen..

Is it blue... is it green ? To really find out, I did a quick chromatography of both inks:

  • pelikan edelstein aquamarine : has a grey-greenish base with very water-soluble blue components
  • pilot iroshizuku ku-jaku : has a solid blue base with very water soluble green components

Although they have very different chemical signatures, the net effect is about the same. But still - ku-jaku looks a bit more blue-ish to me.

Thank you for a most useful shootout and comparison! Much appreciated as ku-jaku is an old favourite ... and I was seriously considering the Edelstein which is available in standard long carts.

 

Having Edelstein and Iroshizuku, think the properties of the inks you describe are quite inherent in their style. Iroshizuku has always tended to being more saturated, smoother (perhaps more surfactant) ink with beautiful shading.

Thank you for the great comparison! I love the colors, but I agree with you. I like Ku-Jaku more.

FAB comparison. Thank you.

Fountain pens are my preferred COLOR DELIVERY SYSTEM (in part because crayons melt in Las Vegas).

I really really like them both. Since Aquamarine came out I have that and Ku-Jaku inked up in pens and they are glorious.

Way back when I made my first order of bottled ink, having no experience, Ku-Jaku was one of my selections. It has never fallen from it's preferred status and I'm glad to see it ranking well with most everyone else as well. A rare occasion of getting it right from the start.

Agreed. Ku-jaku is my choice of the two. There's a certain richness to the Ku-jaku, while the Aquamarine —at least with the bottle I have— is murky but not intense. If that makes any sense...

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..
    • A Smug Dill
      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
