Hard to use!
"I was so disappointed to use the liner for the first time and realize how difficult it is to use even with the clean up pen. I’ve practiced and watched all the videos and still have had no success. I am using the wing magician now with an eyeliner and that’s been excellent. I also find the black is too harsh for blondes with very light skin, I’d prefer a brown or espresso as an alternative to the black."
