Review (5/5): I love these eyeliners.
These eyeliners are bright, easy to use, and very smudge proof. And they stay on forever.... like-"still there the next morning" longevity. The variety of colors match anything, and the brushes are fine enough to make a good wing or cat eye. The eyeliner itself does not clump in the bottle, although I do recommend storing upright to get the most use of all the product.
