Lovely with great shading
I don't usually choose blue-black on the blue-green spectrum, which I think this is technically, but I quite like the rich shading of this ink. I think of it more as a dark teal than a blue-black. The ink is well behaved and easy to clean out of my pens, as well.
Beautiful shading and sheening ink!!!
The Blackstone Sydney Harbour Blue ink is a gorgeous dark but bright blue ink - it has a really noticeable red sheen to it and it shades beautifully with my medium Lamy nib!!! I feel the price is very reasonable for 30 mls of such a nice ink. I believe the ink is medium in wetness and it dries on Clairfontaine paper (with a Lamy medium nib) in about 5 to 6 seconds. When I did a water test I could still see most of what was written - so it appears semi-permanent. I'm just a little bit over one year into the fountain pen hobby & I'm very happy to have found the Blackstone inks!!!!
