Clio Superproof Pen Liner

The eyeliner I use is a Clio product. Among the various Clio eyeliners, I use the Superproof Pen Liner in Black, and its biggest advantage is that it doesn't smudge even after time passes!

Smudge-prone eyeliners transfer to the eye area over time, making touch-ups essential, but this one doesn't smudge, so I'm finding it very useful!

It seems to fade a little as time passes.
