I absolutely love tarte products and this liner stays on all day long for me.

First I Love 90% of Tarte's products. This one is great, however after a few hours at work I noticed that my "perfect" cat eye wasn't so perfect anymore... there was a bit of smudging and it was due to me rubbing my eyes, maybe a light touch. Also I wear eye primer everyday and don't really have oily lids, so that's not the cause of the problem. So when I seen this I was disappointed as this product was not going to be my new eco friendly replacement for MAC fluidline. So it's super pigmented, and I only really tried it the one night. Not sure if I'd call it "waterproof" but for sure long wearing!

It's nice that the brush comes with it. I don't have any complains about it, it does it's job and it's double ended, bonus!!
