Cosnori Superproof Fitting Gel Eyeliner

It's a pencil liner, but it draws as smoothly as a gel. The best thing about it is that it's waterproof, so it doesn't smudge with water or sweat, and the staying power is amazing all day long. It draws clearly and thinly, but the downside is that it breaks easily because it's so thin.

You'll get the hang of it after using it a few times, so it's fine.

It's thin and small, so it doesn't take up much space in your pouch and is easy to carry around. I highly recommend this as my holy grail eyeliner.
