After trying everything, I finally settled on Woodbury eyeliner!

Since I have monolids, I tend to draw my eyeliner a bit thicker, and I think I've tried almost every famous product that claims to be smudge-proof and long-lasting.

Among them, Woodbury is the one I've been using for a good five years now!! Since it's a pencil type, sharpening it is a bit of a hassle, but I'm still impressed by how it doesn't smudge and draws so naturally haha. Unless it gets discontinued, I plan to keep using it for a long time :)
