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

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

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.

Beautiful ink. Well lubricated with subtle sheen creating halo effect.

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!

I asked Appelboom to choose a color for me, cause the one I wanted wasn't available.
I received Pinky and Morning Mist, and it was a very good choice for me ! I like them both. Appelboom has a really nice team, thank you so much ! :-)

Handige fles, prachtige kleuren en schrijft goed. Is dan ook wat duurder dan een flesje Diamine. Jammer dat niet alle inkt van RO te krijgen is in Nederland! Zo had ik bijvoorbeeld graag de Shake'n'Shimmy lijn kunnen bestellen.

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.

Mooie blauwe inkt die varieert van azuurblauw tot nachtblauw.
Geeft een luxe uitstraling aan je vulpenhandschrift.
Wel een wat dikkere inkt

I now own several Robert Oster inks, including Fire & Ice, Fire on the Lake, and Australian Sky Blue. All are very vibrant colors yet easy to clean.

I only own the Fire & Ice ink.
This ink flows very well, and have a decent shading in red which is pretty good under the sun.
It's price could be better, but in general is a really good ink.

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.

Ik heb inmiddels meerdere potjes met verschillende kleuren in bezit. Afhankelijk van het soort papier en de dikte van de penpunt geeft deze inkt een prachtige “shimmering and sheen”. Mijn favorieten zijn Tranquility en Fire and Ice. Aanrader en snel geleverd door Appelboom.
