No need to access the Prefects' Bathroom to enjoy the magnificent mermaid stained glass window! Mermaid window clings measure 11.5'' x 30'' and come in 3 sections that fit together to recreate the iconic window as it appears in the films. To add to the magic, over 20 floating bubbles as well as the golden egg are included! Add them to a bathroom mirror and recreate the scene! Made from waterproof PVC, the designs are visible from both sides of the window. Simply stick them to any smooth surface like mirrors and windows, then remove them without leaving any residue!
