Would pay double for this eyeliner. Whoever the genius was that invented this he should be given an award. I have tried all the high end eyeliners, in an epic quest for an eyeliner that could withstand the test of time. And this eyeliner does just that. I have taken this eyeliner swimming in the ocean (no running), in the shower, and worn it running. As long as there is no oil products this eyeliner is not budging.
