Review (4/5): It seriously does work. But color transfers
They seriously do work. I was skeptical but it was super easy. I just used my own lashes because the ones that came in the pack were too flashy ( maybe good for a party but not for work). So I'm happy you can use it with any lashes. Will be repurchasing!
Edit: the black eyeliner transfers to your upper lids. You have to make a very thin line and make sure the lash completely covers the eyeliner to keep it from transferring to the top lid.
