Sigma BeautySigma Beauty B12 - Bent Liner Brush

BUY at Birchbox

This is the makeup brush you never knew you needed. Its bent at the ferrule (the metal section), putting the bristles at an angle that allows you to apply liquid, gel, or powder liner as close to your lashline as possible. The small, precise tip means you can also use it to trace on lip liner or even create tiny brow hairs with a brow pomade, and the synthetic bristles themselves are designed to hold and deposit product without absorbing it. The brush may be little, but it has a big impact.
