This is great. I personally have naturally long eyelashes. If I don't curl them, they will hit my sunglasses. It becomes a problem a couple hours later, when the curl doesn't stay and mascara has already been applied. Then I am dealing with my eye lashes hitting my sun glasses again. This was a problem until I got this baby! It is literally like a curling iron for your eye lashes. The curl stays all day, keeping my eye lashes in place. This is a must have!
