I always used to use gel eyeliner and had been looking for a good felt tip liquid eyeliner for a long time, tired of having to use a gel pot and a brush because I'm too lazy to clean the brush every day! When I found Stila's Stay All Day Waterproof pen, I was thrilled. It's so easy to use, it's a very intense black and it really does last all day. It doesn't transfer if you get sweaty or oily either, unlike the gel liners I used in the past. I've even taken a shower with it on, rubbed my eyes without thinking, and it still looked completely flawless.
The reason I give it a 4 instead of a 5 though, is because I feel like it dries out and the quality decreases a lot quicker than I would like for something so expensive. It's double the price of a lot of other pen liners and while the quality is there at the start, after about a month I find it a lot more difficult to use (even when keeping it stored upside down to prevent drying out). It doesn't seem to take long for the very end of the nib to dry out, making it very difficult (but not impossible) to get a sharp flick, and when it starts to dry it also gets harder to apply because it causes strokes that I've already made to flake and clump. It definitely hasn't run out either, because using harder strokes and different angles still produce plenty of liner. Maybe this is just a sad fact of felt-tip eyeliner pens that isn't exclusive to this one, but it's frustrating nonetheless.
All in all, it's a really great eyeliner that I will continue to buy (at least unless I find something cheaper that works just as well), BUT for £12-£13 I would expect to be able to use it for longer before having to replace it given that some of its competitors are half the price, and it's something that those of us who are budget conscious might want to keep in mind.
Ok. This product is A M A Z I N G. I am an extremely active person, (AAA female ice hockey) and this is still on at the end of the day. It's on at 5:30AM, I go to school, I have hockey, then I have soccer, then I have more hockey, I get home near 9PM and guess what? My eyeliner is still on! This stuff could stay on forever. But the stangest thing is that it comes off in a breeze! It has unbelievable wearability. Maybe you watched a depressing/sad movie and cried for 3 hours, but your eyeliner would still be perferct. I wear it swimming in the summer and to hockey in the winter, and year round it'll never let me down. I even have crazy oily eyelids and it still works for me, It may be exspensive, but it is worth pe dollar because it lasts for several months.The felt tip won't dry out on you till it is truly empty, and the tube makes it even easier to make a thin or thick line.
HG! i'll probably never buy a different eyeliner. it doesn't smudge, ever, except when i want to take it off with eye makeup remover. the tip is perfect for thin or thick lines; but i do find it hard to apply for tight lining under my top lashes because it doesn't apply well in a watery area.. but honestly that doesn't change my opinion about it overall because it's perfect.
I bought this product because I had a sephora gift card, and my eyeliner ran out. I never expected to fall head over heels! It stays very nicely, goes on very smoothly (i am an extremely shaky person and it still allows me to create a nice line) the only downside is the price, and the felt tip wears out after a little while. but overall amazing product
This eyeliner has very goood staying on power, it does last for 5 hours+. But I don't like its felt tip, it kind of rough on my eyelids. It didnt have a very smooth application. There are a number of other liquid eyeliners that I think are much better than this one.
Best liquid liner I've ever used. I suck at liquid liner (like seriously) but the pen is easy to use. The formula is long lasting, and it is super black. Took off one lippie because of the price tag.
I purchased chocolate brown and the colour never faded throughout the day, the product never dried out, and the felt tip held its shape and allowed different thickness. I do not wear this everyday as it is pain to take off. The easiest for me is to use a q-tip with some coconut oil and then try to erase the line completely.
This eyeliner works so well I turn to it on days I know I will be my busiest or if I would like a more defined eye. It has never disappointed me and I definitely get my money's worth with this eyeliner.
Amazzzinnnggg liquid eyeliner! I love it! I could cry wearing this eyeliner and it won't smear or budge. I love the tip application and how black it is...just purchased my second one! Definitely holy grail eyeliner for me now!!! A+++++
I wanted a navy or deep blue liner, and wanted to try a liquid or gel that would not smudge.(too old for that - it makes me look tired) I bought this in deep blue ( don't know what they called it). It seems to work well - pretty easy to apply ( i am not so good) and it looks good and stays quit well so far. it's a good eyeopening color.
My favorite eyeliner!
Creams and pencils smudge like crazy on my lids so I switched over to liquid. Stila dries really fast upon application and stays on all day. Very easy to use and great tip for fine lines.
My only issue is that it's not build-able; once the line dries, I can't go over it again to add more intensity. If I try, for some reason the felt tip sort of erases whatever I've drawn on. I usually end up going over the Stila with cream eyeliner and checking every hour or so for smudging :(
 Updating to 5 stars! I recently purchased another one because my old one ran out. I don't know if they reformulated it or if my last one was just strangely dry, but this eyeliner is the end-all best eyeliner ever. The lines come out amazingly dark, the liquid comes out smoothly, and I'm just in love all over again. Forget my previous negative remarks!
