Clinique
It's the holy grail.
MAC
Though not as dark as other eyeliners, this gives a nice base if you want to smoke out your look with shadow! Create your cat-eye and then trace shadow underneath the bottom line for a sultry look.
MAC Penultimate Eye Liner, $21
Chantecaille
This liner also has a very fine tip, making it easy to use and can create a nice smooth line. It stays on all day but washes off easily before bed.
NYX
This liner is definitely most cost effective when it comes to liners. It goes on super pigmented and smooth, and the bold color doesn't run.
NYX Felt Tip Liner, $10
Stila
This Stila product is long lasting and goes on strong and bold. The best part is that it comes in a variety of colors so if you want to mix up your look, you can easily add a pop of color.
L'Oréal
Though it doesn't come in pen form, the formula mimics those of the top-selling products and goes on bold and smooth.
Tom Ford
Feel the need for some extra drama? With double-sided and sized pen tips, you can go from baby wing to Adele status in a matter of seconds.
