HOLY GRAIL EYELINER!!! After I saw HeyClaire using it, I had to get it. Since I also have monolids, this is the only eyeliner that is able to hold up with my monolid, oily tears and all. I have repurchased several times and will continue to purchase. This eyeliner lasts for a very long time as it I get about a few months use and never dries out. It's pretty opaque black as well.

I bought this a while ago at Sephora and have been using it to achieve the perfect precise ultra long lasting cat eye with effortless application . I once applied this liner at 7 am and it still looked flawless after midnight.

Great product does what it says and doesn't irritate

I love this liner! I can put it on in the morning and it lasts all day long, and this is not an easy feat because I have fairly oily skin.

This is my favorite and everyday go-to eyeliner!

Pros:
- high precision with the liquid pen & tip
- long lasting wear
- MOSTLY waterproof (if you keep rubbing it with water, then obviously it comes off)
- really good price compared to other brands of similar quality

Cons:
- none at the moment

I've repurchased this eye liner 3 times because it works and it is long-lasting. I was previously using the Marc Jacobs Precision Eyeliner which is great, but I find the extra cost is not worth it. I am seeing the same results with this Kat Von D Eyeliner, and I would actually say its better than the Marc Jacobs one because it doesn't dry out as quickly.

This is the felt tip liner eyeliner (Tattoo liner is also reviewed on here and that is the brush tip). Up until I tried this liner the Stila liquid liner was the best I had ever tried and to be honest I never really found myself going for liquid, mostly just pencil and gel because I found any liquid was just too hard to use. Not anymore! I am addicted to this eyeliner, it is so smooth and it is firm enough with just enough give to make the perfect wing line! It is also very black and dries to a slightly shiny finish which i love so much! I keep trying to use some of my old liners so they don't just sit there and go bad, but then i just regret not using my Ink Liner. it makes such a crisp perfect line , whether you want a thin barely there line or a nice thick Kat Von D style wing. Love! I have been using mine for a few months and it is not even drying up yet, lots and lots of liquidy goodness left!

Best eyeliner I have used to this date!
It is:
-Long lasting
-Easy precision
-No need to reapply several times for even application.
-I also recommend the NARS- Smudge Proof Eyeshadow Base to make it last any event and any hours. It has seriously never smudge with this combination. Even 24 plus hours! When you have a hectic schedule like I do it is nice to not have to worry about your makeup getting ruined during your busy day.

I cannot say enough great things about this liner. Total control of where you eyeliner is going and stays put (through weather, tears, heat, you name it, *no direct swimming though*).

This is easily the best liquid liner I've ever used. The price is steep but in my opinion it's worth every penny. The brush tip applicator allows for a precise line and great control when doing winged liner. This stuff stays all day and is incredibly pigmented.

This is a fantastic liquid liner that truly is waterproof! My eyes tend to water and this is the only waterproof liquid liner that has actually worked for me and stayed put. My only complain't is that it goes on a little drier than I would like (I wish more liner would come out of the tip when applying), I have to go over it a few times to achieve my desired look, however, the end result is a nice bold black line that won't budge! Love it!!
