UD eyeliners are the best I have found. They are easy to apply, they last hours without smudging or smearing. Deviant is my favorite color but I have just about every color and use them all. I can never go without my UD eyeliner pencils. Highly recommend this product, there are none out there that compare.

I work late nights and always have to dress up and look nice during my time at work. With the 24/7 eyeliner i can create amazing colors combined them together and create that dramtic effect that always leaves my fellow co workers in ah how i look. it always brings out the green in my eyes as well. Over all its an amazing product that i would die with out. Also came in handy when i was doing my halloween get up, as a goth girl. Zero brung out some amazing new tricks for me

Let me start by saying that for years I have been a purely liquid eyeliner girl..now woman, until I found these eyeliners. I have tried so many brands of eyeliner and found them hard to put on, dry, irritating and just plain impossible. I first tried the 24/7 eyeliners pencils when I first bought a Book of Shadows. I read that they were CREAMY, LONG LASTING...that they glideeeee....so I had to put it to the test. When I tried them they were creamy, it went on very easily and did not tug my eyelid. I could actually create a straight line with this eyeliner!!! It did not create uneven spotty lines. Since then I have recommended these eyeliners to everyone and now the people reading this.=) These eyeliners are so good that I can apply it and not have to fix it with a brush to even it out, or a Q-tip. I have included a picture that has Rockstar on top and Ransom on the bottom lashline. I applied both of it freehand and with no brush! I love that they have such a great variety of colors with different effects...like metallic, or shimmer. If you have given up on eyeliner pencils that smudge, are hard to blend and apply then give these a shot! They are magnificent and what an eyeliner pencil really should be! =))

That might sound dramatic, but so are these eyeliners! I've never found a more soft, easy to apply, highly pigmented eyeliner than the 24/7 eyeliner. I recently purchased the 15th anniversary set and am in the process of trying all the colors. My favorite colors are definitely Zero and Rockstar.

If you're looking for that little black liner to go with your little black dress, Zero 24/7 is it. It is by far the best black eyeliner I have ever used. It doesn't have glitter or shimmer or sparkle; its a true, matte, and extremely pigmented black. This liner glides on satin smooth and WILL NOT melt off after a few hours, even without primer. However, I find the line it gives is too defined so I like to smudge it up a little bit. I highly recommend Zero as a UD basic product for newbies to the line.

I am deeply in love with this eyeliner, and after being recommended to me I recommend it to everyone I know.

I am the type of woman that loves to wear a lot of eyeliner, especially for those pin up winged looks. I have an oily complexion and most eyeliners just melt right off my eyelid, but not Urban Decay's 24/7, in fact sometimes it can be a little hard to remove. Haha!

The colors are also really vibrant and if you are looking for a really bold and wild look or you want something more conventional this is your eyeliner. To really describe it, this eyeliner has the staying power of any kind of expensive liquid eyeliner. I kid you not I have put this eyeliner on at 7:00AM and it still looks STUNNING at 10:00PM.

Try it, you'll love it!

I LOVE these eyeliners! They are soo easy to use, with a smooth and creamy application and great pigmentation. I own five colors (I definitely want more, especially since three of them are travel sized). I will list them in the order of the swatches in the picture below.

Bourbon is a glimmering dark brown, and whiskey is very similar, but with no glitter. Both look beautiful with gold eye shadows. (Pairs well with the Naked palette)

Rockstar is a dark purple, almost black color, that I wear with my neutral colored shadows. (Pairs well with the Naked2 palette)

And finally, my fun colors are Ransom (bright iridescent purple) and Electric (Bright iridescent teal). They are so fun to wear to a party, concert, or just a girls night out.

My only issue with these pencils is you have to buy the sharpener to go with is (Grind house, $10) but it's not that big of a deal. Great product, try it and see!

Not last for whole day but is the best for me as long as you do not have too oily lids like me. It is pigmented and it is the creamest one I have tried out there. It is great but I hope it could last longer on me personally.

Although, they really need to start making Corrupt in a full size...
