I bought CoverGirl Liquiline eyeliner. It has the eyeliner tip on one end and a smudger on the other. I used for just a few weeks, and now the tip of the eyeliner is gone, inside the housing. You cannot turn anything to make more pop up, and you can't sharpen it, as the eyeliner has plastic over the inside part, not wood. There is plenty more inside, but I just cannot access it. All the CoverGirl eyeliners I've used in the past just pop up once you turn the bottom part, like a mechanical pencil. Am I doing something wrong? I've attached some pics. Thanks!
