You can say that they are like tattoos for your nails. You simply choose the design you want to use, cut it out and remove the plastic. Then, dip it in water for a few seconds, it would come out of the paper easily so you can apply it to the nail. Press it good into the nail and once the water is dry (no time at all!) add your favorite top coat to make it last. If you find empty spaces within the design, you can always personalize it by adding dots around it and make the design come together.
