But cute packaging only goes so far, which is why we're thrilled that the stuff inside is just as good. The felt tip liner is infused with castor oil and jet-black pigment, so it shouldn’t tug on the skin as your glide it across your lash line. And the crisp waterproof line lasts for hours — sweat, beach, pool, dance party, whatever trouble you get into. Because if you’re going to make a product inspired by a feline, it better fierce AF. And this one is.
