Maybe 6 months ago or so? I don't know. I have a horrible sense of time.
I agree, Blacktrack fluidline is a good for a true flat, black paint effect. Sharkskin shadestick is also good. It mimics Graphito a bit more closely in that it has slight shimmer to it.
You can also just use an Eye Kohl (Smolder), Technakohl (Graphblack) or Powerpoint (Engraved). Those would be better as a base though, as they may crease if you don't set them with shadow.
Check your local CCO for Graphito paint though, as they are still floating around.
