My new holy grail!!!!

It is easy to use with it pen applicator. Goes on dark and bold just the way I like it! Does not skip... The best thing is that it is waterproof and last all day. What more can a girl ask for ?! The quality is amazing!

This was the first liquid eye liner that I have ever tried, and I really enjoyed it. I wish the brush was a little bit smaller, but it does make it really easy to apply. I usually apply this just as a thin line on my lash line.

This is my all time favourite liquid liner! Intense black colour in one stroke that lasts all day even with my watery eyes. You can do thin lines, thinker lines and cat eyes are super easy to achieve.

My favourite eyeliner ever! I have super oily lids and all pencil eyeliners and most liquid eyeliners end up smudging and giving me the panda look within a couple of hours. Stila is the only eyeliner that "stays all day" for me! The felt tip is very easy to use and to make a winged look!

I have greasy eyelids, I have previously used Bobbi Brown gel liner, Kat Von D liquid liner, Marc Jacobs Blacquer liner and now Stila Stay all day.
All of the above are good liners but Stila is miles in front of the rest.
It doesn't dry out like the Kat Von D, and is much darker.
It's applicator doesn't feather like the Marc Jacobs liner.
It is pretty much perfect.
The applicator makes it easy to do any line thickness you want.

I would highly recommend it for people with oily eye area as I have repurchased this product over and over again and I have had no luck with eyeliners staying in place except for this Stila Liquid Eye Liner. I have tried the competitor products like Benefit's Push Up LIner and Kan Von D's Tattoo Liner and this one by far is the most long lasting product in my opinion. I just wish that it was a bit more matte in finish and that it was slightly less in price.

very black and easy to apply, no smudge, hold all day. Very waterproof, best one I have try so far. Would definitely buy again but I find it a little expensive.

My all time favorite eyeliner I can not live without! It works amazing and it is super easy to use with its slim pen structure. It glides on beautifully and easy to make the perfect cat eyeliner. I've tried multiple different eyeliners and have to say I always come back to this one!

My all time favorite liquid liner. Stays on. Does not smudge. When you apply it, it dries in place (does not leave that black line on your upper eye lid if you blink right away.) The tip is super easy to use and super easy to create a cat eye or "wing" with. Love the color, the black is very black and bold. I have purchased this product several times.

This is my favorite liquid eyeliner! It comes in the form of a pencil with a nice thin tip, and it goes on really easily. You don't have to press to get a nice line, and it dries very fast! I have had a very hard time making eyeliner wings with other liquid eyeliners but I never have trouble with this one.
This is a good tool for those who are having trouble getting used to liquid eyeliners but really like the look!
