    My favourite eye liner

    This is my favourite eyeliner. It is perfect! Super easy to use, doesn't bleed and stays for hours without smudging.

    Awesome blue eyeliner!

    This eyeliner lasts and it doesn't smudge or smear. The color is the perfect dark blue. I'm going to buy the dark brown color too. I love it. BFF eyeliners are a great buy and I love the felt tip because it gives you better control of the lines especially when you want to wing your eyeliner on your eyes.
