These are water-slide decals, so you just trim them, soak them in water to separate the decal from the backing paper, slide them onto your nail and then position them, then add a clear topcoat. They work best with white or lighter polish. They are not stickers. Original Artwork by revidevi Please note, the white space is transparent. Nail wraps should be applied on top of contrasting white nail polish. Your base color will be covered by decals anyway, so simply use white nail polish as a background for all of your designs! White pearl nail polish works well too. Areas that are white on pictures are transparent! If you use white base nail polish, they will look white on nails.
