This is a very well known line of inks. The the longest time time company produced ink in two colours: black and blue. Then, they issued their ink in blue-black. This is the regular line of inks.
To celebrate their anniversary in 2019, Aurora produced a special line of inks. The range of colours came in a 60 ml bottle. The colours included: red, turquoise, blue, sepia, green, orange, purple, gray and black.
This ink is famous. For many, this is considered one of the best black inks available. The ink has a deep dark rich tone - a very saturated colour. In addition to the dark tone, the ink has good flow.
I like to take a bottle of this ink with me on my travels. It is a good bold black, and I like the small bottle for travels. It nicely fits within my travel journal case.
A word about the bottle. It is excellent in that it is relatively narrow and tall. This makes filling pens with large nibs much easier than shallow bottles where filling is an art of getting the nib to fully submerged in the ink.
The second colour in the Aurora regular line is blue.
It is a good performing ink but there is a hint of purple in the colour. I find that I lean towards other blues more often. There have been times when I have through the ink has too much of a purple undertone, but I find I keep coming back to this ink.
As with the black, in the ink bottle is well designed.
I was pleased when this came on the market. The ink has an equal weight of blue and black. Sometimes blue-blacks lean too much towards black and has no character. There is enough depth of colour that it looks good on full pages of writing. Same good writing characteristics as blue and black inks in the line.
The ink has a reasonable dry time. Somewhere around 7 seconds or so with a medium nib. Of course, if you use a broader nib, so the line of ink if wider, the dry time will be longer. I have not found the ink to lean to bleed through most paper. Likewise, there is no feathering. Even on cheap office paper the inks has a good solid line of ink.
