Cozy cute Bernie decals choose from clear (translucent) or opaque decals. Cha Cha Covers water slide decals are very durable and high quality and use non toxic ingredients as sealants unlike many available on the market. They work well on all surfaces and can be used on natural nails, acrylics or gels. They seal great under a regular top coat or a gel top coat and will last so long as they are protected under a top coat!
