Great product for a reasonable price!

Love the long lasting formula and the sleek bristles. Easy to use and pretty much idiot proof ;P
I've tried many different liners and I keep coming back to this one.

Best eyeliner ever but dries out too fast!

I love every single thing about this eyeliner it’s everything you want an eyeliner to be BUT it dries out so fast. I know it’s not just me because I’ve repurchased 4 times now because I love it so much.

Great quality

Smooth and precise application making it really easy to use. It also lasts all day without smudging. My only problem is after a few uses the eyeliner would no longer come out of the brush. However, if I store it upside down the eyeliner goes back to working normally.

This Stuff LASTS

If you're hardcore about the ethics behind your makeup, your ideals might not align with Kat Von D herself, in which case you should skip this product. If what you care about is quality and results, though, this one is for you. This liner goes on smoothly every time and doesn't budge an inch unless you scrub it away with makeup remover. It's everything you want in a liquid pen liner and then some. For bold black lines, this one's for you.

Good but pricey

I really liked how precise I could get with this eyeliner and it seems to last through the day. It is expensive especially for someone that uses eyeliner almost everyday.

Decent

I’ve been using this product on and off for years. I love how great of a wing I can get, however sometimes it bleeds and sometimes it’s nit black and it’s a super light grey. I will continue to purchase though

I love the liner, but you need to remember upkeep!

I bought this liner looking for something that would last longer than my current liner, which would flake throughout the day. I love the formula of this liner. It stays all day and doesn't budge, and if you happen to have a little breakdown and start crying, your makeup will still look flawless when you're done. However, the one downside that no one ever seems to mention about this product is maintaining it so that it stays in its best working condition. You should clean the applicator when you're done with your makeup with a little bit water, micellar water, makeup remover, etc. and some tissue/cotton pad. The applicator can get all mucked up with eyeshadow and oils from your eyelids that make the colour of the liner fade over time. If you really want to keep that flawless black pigment, you should wipe off the tip of the liner when you're done applying your makeup.

One of my favorite, but...

This tattoo liner has a perfect felt tip makes lining your eyes super easy. It stays on until I take it off. Even if I'm sweaty at the end of the day work out. It does not last very long so you have to replace it sooner than others I've tried. I have a Revlon felt tip liner that lasts twice as long and is cheaper at Walmart. Haven't tried both in water yet.

Nice and black, but sometimes scrapes off product

The first few uses it goes on smoothly and pitch black. At the 3rd use, it starts to get streaky and scrape off a line that was just done. It's alright

Kat Von D Waterproof Tattoo Eyeliner

This unique eyeliner has a fine tip to make sure your eyeliner look sharp and precise either when you're doing winged liner or just a simple everyday look. Very pigmented, very black.
