I asked Joost for help with a dark green colour, without shading, shimmer or sheen, that would be office-friendly.
He recommended this one to me, and I can say I'm very pleased with how the ink behaves. It's a beautiful colour, quite dark but not quite black. It's perfect for breaking away from the usual black, blue, and dark blue colours in the workplace.
Thank you very much, Joost.

Velvet Crush is a butiful purple. As usual Robert inks bahave in a very good way in any fountain pen. I really like this Brand and colour.

These inks are really great and write so well with any pen brand and nib size. The variety is also great and is my new favourite ink brand.

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.

This ink is a perfect match for my TWSBI Eco Caffe and Espresso. It is a nice and saturated brown tone. It provides a constant ink flow and a smooth writing experience.

Ice with a hint of Fire

  • Review Add on: 05-01-2025

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 am so happy I puchased this ink. I love coffee + brown inks so this is a perfect combo. Ink is not dry. It compliments my Leonardo Furore Ginger fountain pen so much. Love 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.
