Review (1/5): Arrived with 3 of the 4..
I cannot wear these out because I can only put them on one eye.. one of the eyelash set pieces were not inside the package despite it being sealed with tape? I'm assuming it is an accident of manufacturing..
I did try to apply the one set that was functional and I really really struggled, I'm not sure what the trick is with these, I tried setting it beneath my lash and closing my eye then putting the mate on top of my lash and it would just end up behind attached halfway down my lashes and barely hanging on. I tried following the direction and doing it the reverse way, with the lash balancing precariously on top of my lashes but doing so much as breathing would cause it to shift, much less trying to adhere it to the lower lash mate.
I have no idea if it's easier on the larger sets, but this one arrived missing 1 and was a b* and a half to attempt on the one working eye I did try it with!
