Fire & Ice is one of the most beautiful sheening inks I've seen. The sheen is not as dramatic as Organics Studio inks, but on decent paper that picks up sheen, the contrast of the blue ink and red sheen is absolutely gorgeous. I think this is a better balance of sheen, to be honest, since you can see both the base and the sheen clearly. It also has beautiful shading where the sheen doesn't show.

Oster inks are always lovely and usually well behaved. Green at night is no exception--a beautiful deep, almost black green. More green shows in wider nibs, less in finer ones.

Love Robert Oster’s selection and quality. Crema is a lovely shade of brown right up there with Lie de The by J Herbin. My only caveat with Oster inks is the hefty price tag, but the quality speaks volumes. Excellent flow in every pen I’ve used it with, and typically vibrant shades of ink.

Robert Oster makes some of my favorite inks. Highly recommend Blue Denim, Melon Tea and Claret.

Sea green, complex and muted but not without a certain brightness. Incredible shading. I love how unique this is, and the color really suits a medium or broader nib. Similar to Kyo-no-oto's Hisoku and J. Herbin's Verdigris in tone, though the color itself is different (I have all three and love them all).

The ink I got was Blue Night. It was not quite as dark as I thought it might be from the ink swatch on the ordering page. Still, it's a nice blue ink with a bit of a grey tone to it. It's fine.

I'm really liking this brand of ink. It was new for me this year, but I have found this product to be great quality. I enjoy the colors offered especially in the shimmer.
