Sometimes the rest of your face just gets in the way when you’re applying mascara. Even when you’re careful, it inevitably smudges on your eye lid and below your bottom lashes. Now there’s a way to prevent these common snafus: Lash Card, based on the makeup artist trick of using a cut out business card. This thick card keeps smears away and can also be used to separate any clumps. It comes in a cute package that slides right into your makeup bag.
