Ink Review #858: Robert Oster Sydney Darling Harbour


Robert Oster Sydney Darling Harbour was the show ink for the 2019 Sydney International Pen Show. I saw some photos of the color online (I should stay away from Robert Oster’s Instagram-he only makes me drool over ink I can’t always get) and was so jealous that I wouldn’t be at the show to pickup a bottle, but Lisa Vanness to the rescue! Thanks to Vanness Pens for providing this ink for review.


The color:

Sydney Darling Harbour is a medium green. It’s almost an unsaturated mint green or dark mint julep.



In large swabs on Tomoe River paper the ink looks more brown when pooled.


Writing samples:

Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.

Dry time: 20 seconds

Water resistance: Low

Feathering: Low-there was some feathering in the flex nib.

Show through: Medium

Bleeding: Low-there was some bleeding in the flex nib.

Other properties: medium shading, no sheen, and no shimmer.

On Staples 24 lb copy paper the ink feathered in all nib sizes and had a little bit of bleeding.

Longer Writing:


I used a Franklin-Christoph 46 Olive Diamondcast with a medium nib on Tomoe River paper. The ink had an average flow.

Overall, I love the color of this ink. It’s a more unique color that I don’t see often in inks. I’m glad I have a full bottle because I think it’s an ink I will use often.
