I can tell you all, after single handedly trying every single black liquid eyeliner on the market, the best drugstore eyeliner is Boots No 7 for $8.99 at Target. Boots is a UK company that has always been the best drugstore ever, in the history of ever and thank GOD they sell their products for us Americans at Target. It’s blackity-black, doesn’t flake and stays on. What more can you ask for?? Get yours here.
