Okay, I got these dispute some negative reviews because I just wanted them for an ugly sweater party. But I have used ALL of them. And if you're having issues, you're not using them right. Firstly, file your nails, and use nail polish remover to get rid of oil/dust. Then put sticker on. I use a nail clipper or cuticle cutter to get excess off, and only use nail file (my own and a very fine grade one) to get the edges just right. you also don't want to be filing on an angle facing down TOWARDS your nail. You have to file gently, and in one direction (so left -left left - or right-righ -right) and file should be making T shape with nail. That way you're not filing the top of sticker off your nail. Then really smooth down the sticker try your best to get any air bubbles off. Then apply a not too thick layer of topcoat. Done. Everyone saying these are getting stuck you're obviously not putting a top coat and sealing any edges. These lasted on me for days. When I wanted to take off also I could just peel them off. But nail polish remover also worked. I do my nails often and wanted to get most so I don't think I wore these more than 4/5 days. But still good wear considering on me a regular manicure will chip in 2 days.
