What it is:

This brush lines your lids with extreme precision.

What it does:

The super-fine point lets you control how thick or thin you want your liner to be. The brush is designed to do most of the work, so you don't need to use a lot of pressure. (Hence, effortless application for an otherwise problem-prone practice.) And thanks to the firm bristles, it's good to use on creams, powders, and liquids.
