All of our waterslide nail decals are printed on the highest quality waterslide decal paper. The high resolution designs are all printed on clear backgrounds. Any white in a design will be clear on your nail. They are slightly opaque, so they look best on a white, natural or light colored nail. Nail Decals can be applied to natural, acrylic, gel or any other artificial nail. All nail decals are packaged in a clear bag with easy-to-follow instructions.
