I use Carbon (naturally Black hair & brows), or I use Print, Suspicion, or even a *little* Blacktrack Fluidline sometimes. All depends on what I have nearest at the time. It's not always MAC, as I have very few MAC shadows. I always use *Dark*
I used to use a Revlon eyeliner/eyebrow pencil...I might try it again...it was my 1st in my Love Affair with Black Eyeliner
I guess it depends on the shade of brown your hair is. When my hair is really dark, i use espresso. When it's a tad bit lighter, i use Coquette. right now i don't use either cuz i'm growing out my brows :/
