Due to working with my hands all the time for many years - tremors, twitching, nerve damage and arthritis makes lining my eyes that much more difficult. Much of the time, after I've spent a lot of time on my shadow I get nervous about trying to line my eyes in a fun way, so I stick to smudging black shadow into my lash line and call it good, even though my heart screams for a wing or something even more dramatic. With this Eyeko liner I can line my eyes with much less worry than I used to have. I've still had issues, but this liner is so easy to use, and much more forgiving than the drugstore liners I've tried. I think I found my fave liner, and I'm not afraid to tell the world!
