Not thick enough so nail imperfections underneath show through. It is not the same smooth finish you would get with a gel manicure. I've also found the nail shapes and sizes weren't quite right for me so lots of fiddly cutting. They say you can stretch them out to fit but they either break or get even thinner if you do that. 3 stars as they do last once they are on even through swims and showers etc. the coral kiss colour is ok but was hoping for a more vibrant orange, it's more muted in real life and a bit peachy. A bigger selection of pedicure colours would be good.
