They come with a cleansing pad that you use to prep your nails. You find the size that fits best, peel off the backing, press on and you're done. That is all. While OF COURSE they didn't feel as sturdy as acrylic nails, they didn't feel like they were going to pop off either. I kept them on for about 48 hours and only took them off because I wanted to, not because they were coming off on their own. They come with a little nail file which was useful because the tips of mine had glitter that made it a little rough. I really loved these and will definitely be playing around with the fun designs in the future.
See aren't they pretty? Not bad for $5!
