Robert Oster Motor Oil is a wonderful subtle off-black with green-brown undertones that give your writing the look of an antique manuscript. Very nice flow and well-behaved even with flex and extra-broad nibs. A favorite!

I have several blue inks, but Soda Pop Blue really jumped out from the pack. It has nice shading properties and the hue is lively yet still useable in professional settings.

This is one of the most beautiful blue-green inks. Lovely shading with a wet flow and a decent dry time

LOVE these ink: I have Black Violet (one of my favorite blackish ink), Great Southern Ocean (bought it out of nastalgia: I miss being camping at the shore of GSO), Bronze (GREAT), and Grun Schwarz (haven't gotten to it much). But after trying many brands, I am very happy to discover R Oster: I love the simplicity and practicality of the bottles and the no non-sense reliable ink of rich colors (well behaved, does not feather..etc.)

I've purchased several Robert Oster inks (all from Pen Chalet) & I think I've picky come across one that ran a little dry but using a wetter nib helped immensely. I live RO inks which is why I have more bottles of them than any other brand.

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.
