Review (5/5): Best Liquid Liner
This is the best liquid eyeliner I've used. It's super easy to apply, and not at all messy or smudgy. The brush is the perfect shape for doing either thin or thicker lines. And it rubs off easy enough with a cotton swab.
My only qualm is that it can look a little shiny in direct light, and I prefer matte. But it isn't too noticeable. Very much recommend.
