Immerse yourself in a rainbow daydream and create beautiful rainbows for your home and family with our exquisite light-catching stickers. 3. **[No Glue, No Residue]** These stickers use electrostatic adsorption technology. Simply peel off the transparent backing paper, spray some water on the glass surface, and then apply the smooth side of the adsorption film to the glass. Recommended for outdoor use. Ensure the surface is clean and free of stains, films, coatings, or other decorations before installation. **Important:** The backing film must be removed before applying to windows, otherwise the electrostatic sticker will come off within a few hours. 4. **[Reusable, Repositionable, Washable]** If you need to clean the windows, you can remove and wash them before reapplying. These adsorption films are also washable with water. 5. [Perfect Gift] Believe it or not, no one dislikes a rainbow.
