Aurora Optima Blue/Gold with broad nib. Aurora makes the Blue Auroloide Optima in either gold or chrome trim, and this is the gold one. Mine has an older style cap band, which I like. I love the blue Auroloide acrylic.
I’m using Aurora Blue ink. It’s just excellent.

Aurora Blue reminds me a little of Iroshizuku Tsuyu Kusa. They’re both what I think of as ‘quiet blues’ – not as loud as turquoise can be, but brighter than the darker blues, including the typical medium blues of most ink companies 🙂

I think that’s true!
I also think I have a sample of that Iroshizuku. I need to try that. You know, because the more blue inks the better.

It’s almost kind of…’radiant’ is the word I want to use, even though it feels corny! It does dull down when dry but not TOO much. It really needs bright-white paper à la Clairefontaine/Rhodia though. I was a bit shocked to see it on cream paper – barely recognizable 😛
