This is a great product. I love the intensity of the black eyeliner and the ease of the pen when applying. This is worth the price and makes a huge difference compared to other similar liners such as Artliner from Lancome.

this eyeliner rocks. It is the only one I have been able to put on with any consistency. The Chanel SA told me to put on some eye shadow powder first with my thin brush, then liner and then more powder. It looks really nice.

What took me so long?! This is one product that went to instant HG status which is saying a lot b/c I don't have too many HGs to begin with. I LOVE LOVE LOVE this liquid liner. I have shied away from liquid liners for many years after one bad experience (I can't even remember what it was) and now I'm kicking myself. This liner applies like a dream and I can finally achieve that thin line I've always been after. The brush is very soft (but not so soft that you don't have control) and it's so easy to quickly and neatly apply the liner. I like the "click base" dispenser. I was very careful not to overclick when I first purchased it and I find I only need 1 click for both eyes if I want a subtle thin line. I will definitely buy this liner again and again.

This is the single greatest eyeliner I have ever encountered. Prior to this, I've been quite loyal to MAC fluidlines, believing that I wouldn't be able to manage a liquid. However, this liner is easy to use, goes and smoothly, creates a fine or thick line easily, and has an overall beautiful look. I have the navy ecriture and it looks gorgeous with my brown eyes (if I do say so myself :)). I got mine on ebay but I actually think this high priced item is worth every penny. This is easily an HG for me and I imagine that will be true for many years to come.
For additional info, the liquid is held in a cartridge and is released by twisting the bottom. The applicator is essentially a brush but not like any I've seen before in a liquid liner (more like an actual brush). If your thinking about this, go for it. Its wonderful.

This is a review/comparison. I purchased my first tube of this liner from Chanel in October at the Saks in Boca Raton and I loved it. It lasted a long time and it was only a couple of months ago that I noticed the pen was dried out and I needed another. On a whim, I purchased MAC's fluidline in June '07 and I liked the color payoff (see review) but it smudged onto my upper lid, causing raccoon eyes. I like the rich dark color of the MAC Fluidline but the Chanel liner can go on a bit sheer yet you can layer it for a darker look without much risk of flaking and buildup. The application process is faster with this pen type applicator while MAC's fluidline requires a brush. I do not have time to painstakingly apply a liner with a brush. I am no makeup expert so the pen is way more convenient and more precise. No constant dipping of a brush into a gel pot. I purchased a second Chanel liquid liner yesterday and I am loving it even more than the first time around. No, and I mean absolutely no raccoon eyes today! The application was faster and after 7 hours of wear, my winged cat eyes still look fabo. I am only taking off one lippie only due to the fact that I wish this liner was a bit darker and not as charcoal/slightly sheer. But, like I said before, this liner can be layered, albeit carefully, for a darker, more intense line. Love this!

Very neat, innovative packaging. Agree with previous reviewers on that the click mechanism is difficult to control the amount of product that comes out, and also the liner flakes off when you go over the line again. But if you can do it perfectly the first time round, the liner stays on ALL day even through humidity and sweat, I'm very impressed with the wear. It comes off super easily with water.

I was seduced by the packaging - but I found that this product seriously underperforms. First of all, there's no way of getting the right amount of product on the nib - you either don't get enough to form a solid line, or you get a big gloop that's impossible to control, and a waste as you have to wipe most of it off the tip. Then when it dries, it turns into a plastic film that peels away if you try to touch up the line or add another product on top.

For a product that costs £16, I expected more, a lot more. I've used drugstore equivalents, such as 17 Soft Liner Pen which gave much better results, and at a price of £3.49.

UPDATE: Two days after I wrote this, the entire nib of the pen came off when I removed the lid. I replaced it but it has continued to come off at random moments.

I went on a search for the perfect liquid eyeliner after L'oreal changed it's packaging--including the brush--for its felt tip Line Intensifique a few years ago. Chanel's liner, around $30 USD, is four times more expensive but well worth it.

This liner comes in a click-style pen (think Stila Lipglaze) with a lovely, tapered brush that has never splayed on me. You twist the bottom, and product comes out. At first, I struggled to get out the exact amount I needed. It was either too much or not enough to do both eyes.

What finally worked for me: I only "click" for new product every other day (I use liquid liner daily). Shaking the pen a few times will give you enough product to use on both eyes. On days I do "click" I brush the sides to clean off any extra goop.

This liner defies the old thinking that wearing liquid liner during the day is too harsh. Applied with a light hand, it's perfect for a simple clean line at work. If desired, shifting your wrist slightly and pushing just a tad harder gives a stronger line for nighttime.

And if you struggle to justify the price, an empty pen and brush are great for applying gel liners :) continued >>

This the best. I am bad at applying make up. A friend thought me the essence of eyeliner. This is my first one and I love it, it give a thin line if that is what you want or clean thick line. It looks like it will last forever.

Probably the best one from eyeliners! Very easy to apply! In love with it!!! It is worth the price!
