This is an absolute staple in my makeup bag - I find other eyeliners, even the ones that claim to be waterproof, just don't have as much staying power, or smudge so I have little bits of colour in the small creases underneath my eyes.

This is the ONLY waterproof eyeliner I've found that is smudgeable, yet stays where it's put, until you remove it. I have the black, the dark brown and a plummy coloured one and I wear one of them every single day!

I've even used them to do winged liner, as I don't have that steady a hand for liquid eyeliners, and the pen liners don't seem to stay on for me and smudge so easily!
