    Good quality

    The tip on this is awesome to work with! I’m absolutely terrible at a wing liner so it was very easy to work with. The quality is really good, a little difficult to take off if you made a mistake but that just shows that this baddie will stay on all night :)

    New Favorite Eyeliner

    This eyeliner is iconic. I’ve been looking for a cheaper dupe for Clinque’s liquid eyeliner and when I stumbled upon this one I was shocked at how much better it performed for a fraction of the price. The pigmentation is wonderful and once it’s on it doesn’t budge. I can seamlessly create sharp wings.

    I highly recommend this product.
