Review (2/5): They're ok.
I wouldn't say these are one step. I tried them as one step and they peel off almost immediately. This time I added a base coat and top coat and granted I do work in retail but I thought since its gel, it would withstand the pressures a little better. I was wrong. But on my toes it last forever and in good condition! The color comes out nice but I still always do two layers.
