I received this ink in a trade with someone on this board.
I have to say that I LOVE the deep dark purple with gray/black undertones. It is definitely purple in appearance, but sufficiently dark to be used for everyday purposes (even at work depending on your field and work environment).
A few key observations:
This ink has a very wet flow and it will feather in a wet writer if used on cheap paper. It really shines in a dry writer with a F/M nib.
I didn’t notice any nib creep.
Bleed through was only an issue if used with a wet writer.
It dries very quickly even in a wet writer (2 seconds or so).
