I love this because it is quick, easy and not messy. The only problem I had with the product was that there were some imperfections at the front edge of some of the nails that I had to file away.
You get a prep wipe and nail file with it as well. It comes with clear instructions on how to use it which are very helpful if you're a first time user like me.
The nail sticks on with gel underneath a plastic film that you peel off easily. It sticks really well to your nail quickly.
