This durable formula glides on like a liquid liner—it gives you the same bold definition, but won’t run when you tear up from a good laugh. (via In Style)

This eyeliner is so easy to use. It goes on smooth and stays on really well. I've tried a lot of different eyeliners, and this is by far my favorite.

Elegantly.

by far the best eyeliner...it comes out really dark and smooth...and lasts all day and night

What the name says.
it goes easy on the eyes, and is easier to apply than regular liquid liner.

Years of searching for a truly long wearing eyeliner have finally (thank god!) come to an end. I know that Brown won an industry "Genius Award" for this product and it is well-deserved. The eyeliner stays put even on my oily skin. It is a breeze to put on (although cleaning the brush is a bit of a pain-don't forget to get all the eye makeup remover out of the bristles by washing with gentle soap and then water, or you will defeat the eyeliner's staying power). I just need to get some additional colors now: the mauve-black with bronze and gold pearl tints is my next Bobbi Brown purchase.

This eyeliner lives up to the hype -- once you've got it on, it doesn't budge 'til you (or your makeup-remover soaked cotton ball) tells it to rack-off.

The trick to getting a really strong line that won't fade is to get a decent amount of product on the brush, but you have to be sure to be careful 'til it's dried out nice and good. Then you're off!

Bobbi is best. (Her extra fine eyeliner brush works a treat with this too)

I constantly am searching for a newer and better eyeliner and I always seem to run back to Bobbi Brown for the Long-Wear Gel Eyeliner. Apply with a thin brush and paint on this black gel for a sleek look. And don't worry if black is too harsh, this liner comes in browns, blues, greens, and purples to soften your look.
