These are great eyeliners! They are like a gel/pencil eyeliner. They glide on smooth and stay all day.

UD 24/7 eye liner pencils are the ULTIMATE HG eye liners in the world! I just disconvered them and I can't believe I was sheltered from these all these years. Am so upset about this. I bought quite a few Rockstar, Bourbon, Mildew, Flipside, and Deviant. They are all of high quality and no smudging at all. I do use their eye primer before and it stays put all day. It goes on super smoothly without any tugging at all due to its creamy texture and the colour payoff is fantastic! Will repurchase these forever!

Rockstar = dark purple that I pair with any purple or brown/nude e/s.
Bourbon = golden medium brown that I pair mostly with brown/nude e/s.
Mildew = mossy green that I pair with mostly green or brown/nude e/s.
Flipside = turquoise greenish/blue that I pair with mostly blue or brown/nude e/s.
Deviant = cobalt blue that i pair with purple or brown/nude e/s if I want to add a pop of colour.

I got 'zero' (black) in the Show Pony Box from Sephora. This is the creamiest eyeliner pencil ever!! I love how it glides onto my lids so easily! I can just quickly throw this on and run out the door. Zero is also really pigmented! The only problem is that during really humid days or if I rub my eyelid, the color seems to fade a little bit. That's okay because I LOVE how creamy and pigmented it is!

I looove these liners! I held off on trying these for a long time but finally I caved in. Yes these are expensive and it gets even more expensive because you fall in love with all the different colors. I first tried Rockstar and Lucky and I loved them so much that I splurged and bought the 15 yr anniversary eyeliner set for $92....I know, I'm crazy! But I honestly felt it was worth it in the end, it had limited edition colors that weren't available in their regular line and each liner normally costs $18 so 15 liners for $92 didn't sound so bad. The set has all the colors you could ever want.
I love how pretty these liners look, I only line my lower lid with these because I always prefer a dark black to line my upper. I love how soft most of these colors are, with other liners I would have to smudge it out a lot because the colors were so harsh but not with these. They are bold but soft at the same time, they remind me of what it looks like when I use to line my lower lid with eyeshadow. Love the look of lining my lower lash line with eyeshadow but the only problem was it wouldn't last and would start smudging quickly. These are the only ones I've tried that last the whole day on my lower lash line. Even wore this while working out and still didn't smudge! I'm still in awe of how I don't have to look like a raccoon anymore at the end of the day. I haven't tried lining my waterline yet so I'll update once I do but just the fact that it lasts on my lower lash line is enough to make me love these. These are sooo creamy and easy to line, I usually hate pencil liners because they are too hard and don't make a smooth line. With UD's, I can create a smooth perfect line with no skipping.
FYI-For anyone that has had a problem with this pencil crumbling when sharpening, don't use UD's sharpener. The anniversary set came with a free sharpener and it really sucks. I can't seem to get a good point with it and half the time the tip will break off. I prefer using MakeupForever's sharpener, always gives me a nice point and doesn't break the tip off.

These are my favourite pencil liners!
I have the Zero/Whiskey duo from the Naked Palette & Flipside.
If I hadn't gotten the Naked Palette, I never would have tried these & would have been missing out!
These are really pigmented & last all day on me. They apply so easily & blend out really well.
I really like the colour selection of these & can't say enough good things.
They are over priced for eyeliner pencils, but, they are worth it because they perform so well! continued >>

*LOVE!* if you can catch these in a package deal, then they are so worth getting. otherwise, i think they are a tad too pricey. either way, these rule. i use 'electric' as a base ALL the time & absolutely love it. i recently purchased the 15 year anniversary set & am still drooling over these colours. they're fantastic bases for coloured eyeshadow & will last you ALL day (especially with a primer underneath, your shadow won't budge!) love these, i will forever buy them :D continued >>

Bought a set of mini pencils around Christmas. Love the colors, especially Binge. Stays on all day for me even w/out primer.

My eyelids: dry but tend to get oilier near the lash-line by the end of the day

Packaging: standard pencil with cap; b/c the pencil is so creamy, you'll need to sharpen frequently

Application: easily applies onto lid

Formula: very pigmented, creamy, but definitely not long-lasting

Durability: does not last and has creased into folds by end of day; how long it lasts depends on what sunscreen, foundation and powder I've applied to the skin around my eyes (e.g., wears better over Revlon Colorstay Foundation without any powder to set compared to over MUFE Face&Body with no powder; last longer over Shiseido SPF55 Creme but over the euro-sunscreens, forget it lasting even 2 hours...)

While I love Oil Slick (perfect grey/black with not-over-the-top glitter) and 2 other colors, these eyeliners' performance absolutely do not warrant re-purchase. continued >>

I've got this is in Whisky, Zero and Gunmetal. I love all three colours (even Gunmetal which I thought would be a bit out there, but no it wasn't!).
I got to say, these have got to be one of the best eyeliner pencil I've ever used. They are super smooth and soft. They blend soo well for smokey eyes and they are super durable.
I would never use these if I want a define line, these are just soo soft that they smudge really easy. they are only great to smudge, which I tend to do all the time anyways,
Urban Decay extremely hard to find here in Australia, and even if we do find it, it always the discontinued stock from USA. I've brought these online, and I know I got ripped off, but even soo, I still would repurchased these again. I will be looking at getting a few more colours.

This is the best eyeliner I've experienced so far. I am rubbish at doing eyeliner and this glides on beautifully and makes the job SO easy, gives perfect lines each time! I love how it's so easy for me to apply and because it's soft I can smudge it easily to get the desired effect. It is quite creamy as well, which I like personally as I don't like the tough "pencil-like" textures of some eyeliners.

The slight downfall is that it does fade slightly by the end of the day - but I don't mind too much, I guess if I did want it to last I would opt for a liquid liner (which I wouldn't because I'm not skilled enough at application!) Also the range of colours is great, I love "Honey" and "Zero" in particular. A difinite recommendation from me!
