Note: I do not wear mascara that often, and my eyelashes are stick straight.

This product lengthens my lashes a little bit (due to the fibers it has) and definitely holds the curls for at least 5+ hours. But, since I don't wear mascara that often, I noticed that my lashes got tired because it was curled for so long--similar to how your head hurts after you have a super tight ponytail for a long time.

The product was kind of hard to apply since my lashes are also kind of short but the curved wand helped with the inner and outer corners of my eyes.
