So these are really neat! I love nebula so these are right up my alley. I will say I used them over my do because my nails are pretty thin. And my first time using them i can tell there is a learning curve! I think you need an even a you can get layer of adhesive or there will be faster drying times and the foil won't stick. But thankfully I used colors that blended well so you can't tell. Another good thing is that if you need up or you don't like the design on the nail it is easy to file it off! I will definitely be buying others to decorate my dipped nails!
