I really loved the formula and staying power of this eyeliner duo! The pencil is super smooth and creamy, and easy to apply. After it goes on, you have a bit of time to fix it before it sets, and afterwards, it’s definitely smudge and budge proof. I especially love the formula of the liquid liner because it’s so black and once it dries, it doesn’t go anywhere. I have pretty oily lids that are also hooded as well, and I also tear up really easily, so that combination means a lot of eyeliners smudge and rub off all the time, and don’t last. The liquid liner lasted all day, even through a lot of exercise and sweat, which was amazing. I also loved that the liquid liner had a brush tip.
