A brush liner that doesn't smudge, is waterproof, and lasts for a heck long time!!! Once I used the Loreal Super Skinny Eyeliner and the Maybelline Masterprecise Eyeliner and those eyeliners smudge so much and gave me raccoon eyes even though I just blinked. However the Clio eyeliner never did smudge on me. It does wear off after some rubbing on the eyes however it lasts so long.

Pros:

- last long (tried it for 12 hours with 1 reapplication after eyedrops and rubbing my eyes)

- don't smudge (can flake a teensy bit, but no smudging)

- the tip is flexible enough for a cute wing, and firm enough to not stab your eye accidentally

- cute packaging, and the gold lettering on the eyeliner looks sophisticated

- comes with eyeliner remover (although regular eye-makeup remover works too)

Cons:

- less dark black than some eyeliners

Overall:

This eyeliner is very similar to the Physician's formula eyeliner, except that it lasts 2 hours longer.I will always have this eyeliner in stock forever!
