A very nice and pleasant ink for anyone searching for a rich yellow with great shading leaning into a deeper orange and brown.
As always, Robert Oster inks are well behaved and are suitable for all kinds of nibs and filling systems with little maintenance even after drying out.

Review Title: Ice with a hint of Fire

Review Add on: 05-01-2025
Average Rating: (5)

This is a very nice and well behaving ink but the fire part, that red sheen, is very subtle. For some that can be a negative, for me it is a positive because it occurs only occasionally it is more special and the more I enjoy it while using it.

I purchased Evening Sapphire. I don’t know why but Robert Oster Inks have a special spark for me. It hits different than other brand inks. I love the dusky light blue color and the shading of this ink.

These inks are always incredibly well-behaved and come in unique colours that I haven’t seen from other brands (especially the Shake ‘n’ Shimmy collection). I only wish they came in glass bottles, but that’s a minor complaint

Review Add on: 25-06-2023

Tested with Pilot Capless 'B', Clairefontaine 90 GSM paper.

This is my first Robert Oster ink. Summer Sky is a light blue color that is comparable to, for example, Pilot Kon-Peki or Akkerman Passage Blue. This ink is not particularly dry or wet and has quite a bit of shading.

Review Title: My favorite Blue Black - Midnight Sapphire

Review Add on: 21-06-2023
Average Rating: (5)

I have some blue black in my ink collection that are all great inks, but they don’t have the right colour I was lookin for. At the Appelboom shop in Laren I browsed through a binder full of colour examples. I decided to go for a bottle of Robert Oster Midnight Sapphire. Lucky for me they had it in stock.

The ink is now in a pen with a broad nib. It flows well and the pen is writing very smoothly with it. On average, depending on paper it has medium shading.

Some might call it more of a dark blue than a blue black. It does depend on the paper but it’s a blue black on (white) Oxford paper and fountain pen friendly printer paper. In some cheap notebooks the pen writes wetter and the it becomes more of a dark blue.

What I like is when there is decent shading. The dark parts become dark blue and the lighter parts medium blue black.

Review Title: Beatiful Blue but dry

Review Add on: 09-06-2023
Average Rating: (4)

Hi,

I have been wanting this color for awhile. Finally pulled the trigger. I do enjoy it when laid on heavy which gives it a wonderful red sheen. I would avoid this on any nib below Medium. I don' t think you would get the same experience. I was using the Galen Leather Everyday Notebook with the original Tomoe River paper.

Review Title: Perfect for me

Review Add on: 21-11-2021
Average Rating: (5)

I was looking for a very dark green ink for a long time one that was dark enough that it wouldn't look out of place in a business setting and bright enough that it was not just black with a name reminiscent of some other colour that may have been added in small amounts.

Enter RO "Green at Night" it is exactly the colour I have been looking for a green to petrol blue that goes down noce and dark but when you see it it makes you question the colour. Perfect.

The ink flows well and I would consider it to be a thin "watery" ink. This is not a bad thing at all. Even in one of my high flowing Italian pens this works a treat.

The water resistance is not good and if you are writing something that has a possibility of getting wet it will not hold up - not that many fountain pen inks will so not to dissimilar to most - other than that it is a near perfect ink and I will be adding several more to my collection as well as stocking up on my new signature colour.

Review Title: Robert Oster Signature Turquoise

Review Add on: 09-01-2021
Average Rating: (5)

The ink of my choice was not available, so Joost choose another color for me. He did a great job with that. I love the RO inks, bright, vibrant colors, great flow, very useful bottles and not unimportant: the name of the ink is on the top of the cap, so I don’t have to take all my bottles out to find the one I’m looking for. I wish all the brands did that! This turquoise is on the teal-side of the spectrum and perfectly fit with my Wahl Eversharp Signature in Jade. That is the same material as the Leonardo Furore Grande Smeraldo is made of, so that would be a perfect match too!

Review Title: RO: Velvet Crush

Review Add on: 22-12-2019
Average Rating: (5)

RO: Velvet Crush

I bought this ink thinking it would be a good mimic to Lamy's Dark Lilac. While close, not close enough in my opinion. You need good paper (rhodia, tomoe river, etc) to get this color. At the same time, it may get closer to that effect if it reduces/evaporates. Since this is a purple color, it may have flow issues for some people. You can solve this by adding a drop of dawn/liquid dish soap.

RO Grey Seas: This ink is a light Greyish Blue color. This ink in my experience does represent itself better in broader nibs as most do, or at least those with better flow back (too much and you get away from the Greyish Blue color). I have not had any flow issues with his ink yet. The photos you can find online for this ink are a pretty good

I love Robert Oster inks. Well-behaved ink and nice to write with, but it’s also fun to make art with them. If you think Summer Storm and Graphite are grey and black, add the ink to a wet surface and you’ll be surprised by the colours appearing.
Of course the service by Appelboom was also good, as always.

I now own three inks from Oster: Grün-Schwarz, Burgundy and Fire+Ice. Each has a character of its own, that I am very fond of. It flows smooth and leaves lovely shades and the occasional sheen as well (I use them mainly to write, so I am mainly using them in fountain pens). Find your favorite color and go for it. I did and I am happy with them.
