I'm a liquid liner kind of girl, but after discovering MAC's kohl eyeliner, I always have to have it in stock. I know it's a bit pricey, but it lasts me awhile and never fails me. I can smudge it on with no tugging, and it provides a rich consistent color every time. I don't have to sharpen it often and I never have the issue of undereye makeup smudge; it seems to know to stay right in place! I have a 60's eye makeup sort of thing going on, so this works great for undereye lining but also doubles when I don't feel like waiting for my liquid liner to dry. Invest in this wonderful product!
