They're little sticker style decals that you put over the top of polish, or on a bare nail, whatever suits your fancy. Here, I used them over Ulta3 Black Satin which I had taped off with Nail Vinyls for a bit of negative space type thing. I also tried it matte and glossy. I prefer it glossy for once!
I did also find that you have to take these off the plastic with tweezers, and I did manage to tear a few slightly, but you can't tell at all. Overall, I dig these! If you're keen to try them, or anything else Born Pretty Store has on offer, please, use my code AFL91 for 10% off!
