L.A. Girl Ultimate Intense Stay Auto Eyeliner, Ultimate Black GP321

Best one I have found yet for the waterline. It will smudge eventually, but last longer than any other one I have tried.

Again a must have. Last all day. No smudging at all. A must have

In love with this eyeliner. It is very black and goes on smoothly. It is definitely waterproof and stays in place. I use this every day and it never runs even in humid conditions. I will never NOT buy this eyeliner!!

I love it! It’s great for my waterline and it’s pretty pigmented. I would definitely recommend and I would personally repurchase if needed. It also has a pretty smooth application.

Good eyeliner at a decent price. Tip will air dry out if not capped right after using. Can then be hard to line without wiping tip with tissue to expose undried liner. Long lasting.

The best waterline eyeliner I've ever used! Comfortable, waterproof, long wear! Great price! So glad I took the chance. Beats all the many 20 dollar eyeliners I've tried out there. 5 Stars!

The best black eyeliner for the water line that doesn’t budge and has great pigment!

I absolutely love this eyeliner. It smooths right into my waterline with ease. The tip is great for drawing a wing on the outside of my eye and the inner also. Very very black.I hope they never change this formula. Im buying 2 of every color right now!
