Robert Oster Signature Ink Grun Schwarz

da vinci

Recommended Posts

With apologies, this is something of a quick and dirty review. I like my inks not to sheen and to be dark, preferably black with a nint of [purple/red/blue/green etc] for use in a professional environment without "raising eyebrows" :)


I particularly like dark greens, and read the reviews of this colour avidly.


For full disclosure I was given a bottle of Robert Oster Signature Ink in the Grun Schwarz colour by Mr Kirit Dal, who is a seller of Aurora Pens, at the South West Pen Show in the UK earlier this month to try as an alternative to my usual Aurora Black. There are many other distributors of this ink.




The above writing sample was written with an MB Woolf with a medium nib on a spare page from my Tomoe River papered Hobonichi Planner in Cousin format from 2016.


I am delighted with the colour, comparing favourably, to my eye at least, to Diamine Green Black and Sailor Miurai inks of which I have a bottle.


The ink flows well, is saturated (I am not fussed on shading either), and seems relatively wet.


Overall, I am looking forward to using this ink.


I am slightly sceptical of the new generation of inks, one of my principal criteria for buying ink being the lack of risk of staining and the easiness to flush a pen after use. I haven't been able to subject the pen with which this ink is filled to either test yet.


I hope this short review will prove useful to others searching for dark greens! :)

I have it and I like it. I didn't notice any disturbing things. It is wet, well behaved ink but... I'm using it for now only in Lamy with stub (at least for a month)

I'll try it in others pen, hope soon, then I could tell more ;)

Thanks for your take on the ink. I also really like it, but had no similar green-black to compare it too. Glad that it can hold its own compared to the competition.

Short question : is it similar to Diamine Green Black ? If it is - I might get a bottle of the latter, and do an ink shoot-out to compare them in detail.

If anyone has some of the old Robert Oster 'Black' from when he was selling his inks exclusively from his eBay store (early 2016), this is the same ink!

      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..

      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
