this review title is: elf eye liner fail and the content is: i am usually thrilled with elf products but this one was a disappointment i realize that one cannot expect greatness from a cheap liner but based on the performance of many of their products i at least thought i would get some wear out of this i was incorrect there was little to no liquid liner flowing from the tip and the tip felt tough like it was pulling my lid and as far as it being water proof i would have to argue that it is impossible to test that as it is difficult to apply i would not buy again better off to add a few bucks and upgrade to a better product.there are other information for this review, one is this reviewer did purchase it and the other is 5 people think this review is helpful.
