must be knockoff literally does not stay on nails [SEP] i thought this was a great deal and unlike other reviews i got all different colors in my pack of i was so excited i ordered my mom a set too should of tried it first should of known it was too good to be true this stuff does not stay on your nails it must be a knockoff or something but it is terrible and a waste of money i am talking doesnt even stay on for half of a day it doesnt matter how much dry time you allow for as soon as a liquid touches it or your bump it your nails will be ruined also when you apply the sally hansen miracle gel top coat you have to be incredibly careful and barely apply or it takes off whatever polish this actually it do not buy i wish i could return but by the time you use and realize how crappy it is its too late
