Aurora Optima Blue/Chrome with fine nib. I do keep using this pen. It’s hard not to. Also my friend just got one, so we are pen twins, and I had to get our two matching pens together on a playdate.
Her Optima has Aurora’s cursive italic, which is wide and really neat. It is a very crisp italic, with amazing line variation, and it wrote with the lightest of touches. Mine has a fine nib.
The ink is Bung Box First Love Sapphire. In this pen, it really has sapphire sparkle.
