Destructible Holographic School Window Decals are our specially designed Parking Permit Decals that break apart into tiny pieces once they have fully adhered and removal is attempted. These decals are made from destructible polyester with a sparkle finish that refracts light into a rainbow pattern. Installed outside the window, our destructible decals feature a holographic pattern that provides extra security and makes these decals hard to counterfeit and easy to authenticate.
