Totally devoted to these eyeliners since day one. You do need a primer as it creases like crazy. Regardless of my eye color i have bought almost all shades. Recently saw a trio - the smokey nudes with platinum liner (sigh) went back and it was gone. Always used a coupon and bought on sale too. I use a brush to define the line after applying, I've also smudged it at the ends to elongate my eyes using same brush. Paraben free is a requirement for what goes on my face. These are a keeper.

I freakin' LOVE these pencils!!! I have always had oily lids and have never, ever been able to use a liner pencil for two reasons: 1. They'd smear and 2. I could never get down into my lash roots with a pencil (and that is a HUGE makeup peeve of mine). The new breed of liners - gel pencils - hit the market and I loved their staying powder, but I'm terrible at sharpening the !#$@ things! And still, the point was never fine enough for me to get down into my lashline (I have a bit of an edge at my lashbase that requires either a very sharp pencil point or a brush, which is why I've always loved and used gel liners). I first bought a set of these PF liners and it was LOVE, omg. The tip is small, the shades are amazing, they are automatic, the line lasts all day long in any weather and I can tightline with them and my eyes don't water (hello Prestige Total Intensity) and there's no transfer to my lower waterline. I have nearly every shade set and keep a black and brown pencil my beau's house too. I use the lighter shades beneath my lower lashes (and it LASTS). I do wish PF would make a TEAL color group! Love the blue, the green, the purple, the smoky, the nude; in spite of the name "Shimmer Strips" the shimmer is not terribly obvious, if it is at all. The colors are rich and pigmented. I have a serious passion for these things, you guys! Whenever they're on sale I buy more. I hope my gel pots don't dry up, but it's just too easy and effective to grab one of these PF pencils, line and go!

You've got to try them!

I've gone through two sets of these in a span of about three years. Because I'm just not sure if it's worth it. I love these things for several reasons. They really do enhance your natural eye colour. It's fun having the different style suggestions on the box and using the different colours in different ways to experiment with a variety of looks from natural to dramatic. They go on easy. They don't clump up or smudge too bad. All around, they are awesome. I'm a very serious eyeliner girl. I can abandon all my other products if the occassion calls for it, but not my eyeliner! The one thing I really hate about these that makes me debate buying them again is the fact that they use up so fast. I'd rather have a proper pencil that requires a sharpener than these enfuriating plastic twister things! It sounds like a good idea, but it really isn't. You loose too much product to the plastic clicking thing. If you twist up too much of the product, it will just snap off when it touches your skin! It's impossible to know how much is two much because I've had even tiny chunks jump out of the tube! You have to be careful not to drop these or let them rattle around too much with other products in a makeup bag. It breaks the delicate eyeliner inside. It's basically like a mechanical pencil that you twist instead of press. And you know how finicky those are! It's a good idea in theory, but for the amount that I use eyeliner - everyday - I'm just not convinced this is the way to go.

I have this in the Nude pack with a nude pencil, a shimmery black and a shimmery brown. It smudges on me within the hour and the texture is very dry to work with. The shimmer makes it unsuitable for use on waterline. I would not repurchase.

Two Shimmer Strips eyeliners were included as a bonus in another product I purchased. One was Espresso: a rich, dark brown. The second was Illuminating Black: standard black. These liners are best for use under the eye, IMO. The configuration is a thin, twist-up style that is rather fragile but very lasting on the skin. They are a little on the soft side so you have to be careful not to press too hard to avoid crumbling/breakage. For this type of delicate eyeliner, this one performs well.

Nothing special colors are blah..

I really like the look of these liners, however nearly minutes after applying them I had puffy eyes and a stuffy nose. I have never been allergic to anything nor have I experienced a reaction like this to make up so watch out!

I normally love Physicians Formula. Have purchased so many of their products. This one however is a very big leg-down. Every time I went to twist it or sharpen it, it would crumble. The purple eyeliner in my trio wasn't very easy to put on and you couldn't see it very well. Bottom line is this one is a dud. Sorry Physican's Formula, have much love for this brand as it is my fav but not this particular product.

Three words: I can't even.
These eyeliners are absolutely amazing. I bought both the Nude and Brown eye trios. I swatched a few on the back of my hand and ran them under water while rubbing them REALLY hard. Of course, they faded the slightest bit since I was pretty much sloughing of dead skin cells, but otherwise, the line didn't move AT ALL. VERY impressive. Next, I lined my eye with the Champagne shade from the Nude set. Champagne is a light, somewhat shimmery brown but ever since I first started wearing makeup, I always used the blackest blacks for eyeliners and mascara, so of course, I was hesitant about buying these initially. But even the lightest shade made my eyes look bolder without being obvious that I was wearing makeup, which was shocking. Then, I tried rubbing the eyeliner off with a wet paper towel and the eyeliner stayed put. For someone with oily Asian eyelids, this was like a miracle!! Now I don't have to worry about raccoon eyes throughout the day. These lines really just stay put unless you use makeup remover to wipe them off. Surprisingly, it doesn't take that much makeup remover to wipe these off unlike some other eyeliners, so that was also a plus. I am completely sold. I will probably be purchasing these for the rest of my life :)

Amazing eyeliner -- can't believe how long these stay on without smudging! I usually line the top lids with liquid liner and my bottoms with these and I am good for the day without needing any touch-ups! I got the nude trio. I don't usually wear liner on my waterline, but I have with these before and they lasted much longer than other brands that I've tried. My eyes are watery - I wear contacts and I have not had much luck with liners on the waterline, but this was was pretty good! Love the twist up design -- no need for a sharpener! I highly recommend!
