The Kat Von D Tattoo Liner in "Trooper" is THE ultimate black eyeliner!!! It is my latest holy grail, and I am never looking back. It is applies blacker than black, and with serious precision. I have shaky hands, so I prefer eyeliner pens with felt tips. I have tried almost all the drugstore eyeliner pens -- NYX's Super Fat Eye Marker is nice at first, but doesn't deliver opaque black ink, and the pen itself dries up quickly. Rimmel's ScandalEyes Micro Eye Liner comes super close as a drugstore dupe because it has a thin and precise felt tip, but it falls short in delivering an opaque and fluid on the first run. I have to go over my line a few times to get a suitable opaque line -- not a big deal by any means, but the KVD conquers a dark opaque line in one stroke. I must admit, though, that ScandalEyes is a great beginner's eyeliner not only because it is waterproof and so affordable, but the tip is a little more stiff and allows for more control.
