I personally think a girl can never have enough black liners! I just recently ran out of mine so I figured I could give this one by p2 a go!
As you can see from the picture above the felt tip is very thing and makes it so easy to get a nice, crisp line!
Now the bad part: even though it claims to be black I think it's more like a dark blue. The pic here is from when I removed my make up and I think it's pictures the blue quite nicely. Also when I tried to apply it over a normal eyeshadow it doesn't even show up.
