This long lasting Eyeliner is the perfect brown shade for my eyes. I tend to avoid black eyeliner because makes my traits appear too heavy but this brown eyeliner looks great on me!

Love this eyeliner. I have sensitive eyes and this doesn’t irritate them. Stays on and doesn’t smudge either.

I received this as a free sample from PINCHme. This has great pigment and shows up clearly with just one swipe. It didn't irritate my eyes at all. I like the color and the ease of use. It didn't even come off in the shower until I used face wash, so it's definitely waterproof.
