I love, love, love this liner, the super thin brush is great for me because I do like to accentuate my upper lash line but I like to keep the line pretty thin, the formula is really great and dries really nicely it lasts all day and because its so black it makes my lashes look nice and thick without me having to draw a thick line. The great thing is if you are someone who likes a thicker line you can just draw the line how you want it to look, because you have complete control with the applicator. I have repurchased this and will if its finished I'll repurchase it again.
