    Holy Grail

    I restock this liner every single time. It does not budge and it lasts through any weather. The thin brush tip is the best.

    This LASTS on older eyes!!!!

    Most long-wearing and waterproof eyeliners do not live up to those claims on older skin. This eyeliner absolutely does live up to hype and I'll be trying other colors.

    Best eyeliner ever!

    This is the best liquid eyeliner I’ve ever tried! Super black, glides on like a dream and does not budge for at least 24 hrs! It’s hard to get off but that’s kinda the point for me! Will definitely repurchase in all the colours!

    Best eyeliner ever!!

    I've tried countless eyeliner brands but this one is the best one yet. I always get compliments when I wear it.

    I have hooded eyelids so I need to draw a pretty think line for it to be visible, this one doesn't dry as quick so gives me time to go over it a few times to create a crisp line. Some eyeliners dry too fast and end up peeling off when you go over it again.

    I always order 6 at a time to always be stocked up.
