I love Etude House’s eye liners, especially the slim line. I have a weird eye shape and this eye liners are the only ones that help me to line them as I want.

The formula is amazing, they are waterproof and smudge proof. The color is a beautiful and natural light brown, ideal to achieve a natural look.

Downsides:
-they aren’t retractable however, the box that it comes with actually warns you about it.
-they come with only 0.08g so if you use them daily you’ll ran out of product really fast.
