Dolphin Decals & Stickers We offer customizable vinyl decals available in any length and width. All of our decals are die-cut from solid-colored, self-adhesive vinyl, meaning your design will not have a background. Please refer to our color chart for available options. These decals are pre-masked and ready for application. They can be easily applied to windshields or any smooth surface, such as a vehicles body. Detailed installation instructions are included with every order to ensure a seamless process.
