At first glance, this liquid eyeliner may look a little different. That's because it features a thick casing. While this may seem inconvenient at first (you can't quite fit the thing in your pocket) it's actually one of the things that makes this eyeliner a winner!

The Eyeko Fat Liquid Eyeliner's thick marker-like shape is great when it comes to the application process. For one, it's helpful for those who are just starting to experiment with bold looks like a cat-eye since it's so easy to hold on to, even with unsure, shaky hands. But even if you're an eyeliner expert, using this product can be super easy and can save you time getting ready every day.

This liquid liner boasts a long-lasting formula that doesn't require touch-ups over the course of a day or long night. Additionally, the ink has a conditioning effect thanks to the fact that it contains algae extract. That means the liner will actually keep your lids healthy and moisturized instead of completely drying them out like many other eyeliners do.

If you love a good bold look, this eyeliner is right up your alley. Not for the faint of heart, this product comes in a carbon black color, helping to make your looks more dramatic than ever before!

While this eyeliner isn't waterproof, it does have its benefits. While many other "waterproof" liners stay on through rain or shine, it's nearly impossible to get off. But with this eyeliner, when it's time to take it off with makeup remover, it comes off easily and doesn't require you to scrub it off with a cotton ball until your skin turns red.

There are many reasons why so many women are in love with this Schwing Liquid Eyeliner by Balm Cosmetics. For one, it has a super-matte finish that's really pleasing on the eyes (in more ways than one), and its cruelty-free formula proves to be great for all types of makeup-wearers.

The creators behind this liquid liner definitely kept usability in mind when coming up with this stuff. That's because putting on the liner is a total breeze. Unlike many other liquid liners, you don't have to wait a long time to continue working on your eyes in fear of smudging the lines. Schwing Liquid Liner dries quickly so you can save time getting ready.

This liquid liner also boasts an ultra-thin tip, allowing you to form all kinds of different designs on your lids. Whether it's a subtle lined look or a draw-dropping cat-eye, the applicator makes it possible to do just about anything.

And while many other liquid liners feature a shiny glow, this liner has a matte finish. In addition to drying well, you can be sure your liner won't flake or smudge throughout the day.

When using this liner, you likely won't have to reapply it throughout the day, but if you do need a touch-up or two, this eyeliner is easy to tote around thanks to its cute, compatible size. Seriously, you can fit this thing right into your pocket!

Sometimes when creating fun, dynamic eye looks, it's all about the applicator you're using. In the case of this liquid liner by Revlon, it's all about the details.

Since the eyeliner boasts an incredibly thin tip, it's the perfect makeup tool to create one-of-a-kind designs on and around your eye. Whether it's a sultry cat-eye or an ever-so-subtle outline on your lower lash line, this ultra-thin tip makes just about anything possible.

For people with sensitive eyes, putting on eyeliner can become somewhat of a struggle. Between the burning sensations and stinging when the liner comes into contact with the eye, doing your eye makeup can be a total nightmare. However, this Revlon makeup is ophthalmologist tested, meaning it's a great option for people with sensitive eyes and skin.

This liner also promises all-day wear, so you never have to worry about reapplying it throughout the day. However, if you do want to change up your look from daytime to nighttime, the eyeliner is super compact and can easily fit in a small purse or pocket. The eyeliner is also smudge-proof and waterproof so you can be sure it'll stay on.

And if the color black is a little too boring for you, Revlon offers this eyeliner in an impressive 7 shades. Whether you love a bold, colorful look or a more classic feel, there are plenty of wonderful colors to choose from.

Unlike other eyeliners out there, this brush and smudge-pot combo gives you ultimate control as to how much makeup you use at a time. Instead of applying a soaking wet applicator to your eye, you can put as much or as little gel onto your brush as you'd like, helping you achieve the perfect eye looks.

This gel is very pigmented and can give you a rich black or brown finish (depending on which of the five shades you choose to use), and boasts a unique shine that many other eyeliners fail to have. The gel sits in a smudge pot that comes with an air-tight lid ensuring your gel stays usable for months to come.

This eyeliner features a special liner brush that you can clean in between uses to ensure it stays clean and bacteria-free. The brush is also very easy to hold, giving you excellent control as you attempt to make fine lines and winged tips around your eyes.

The gel in this liner is waterproof and smudge-proof. It also is designed to last a full 24 hours, rain or shine, tears or no tears.

When using eyeliner like this, there are a couple of things you can do to optimize its wearability. One of the best tricks? Put some powder foundation or eyeshadow on your lids first, giving the liner something to hold on to. This way, your eyeliner will look just as fabulous at the end of the night as it did when you first put the stuff on.

That's right, you can wear this liner for up to 12 hours without ever having to reapply.

To make sure you get evenly distributed product with each use, store the liner horizontally.
