Double Sided Stickers: same visual effects inside & outside of windows. Made with PVC material printed on BOTH sides. Great Halloween decorations! Size: the package comes with 9 sheets of Halloween Stickers and each sheet measures about 30× 19.5cm/11.8× 7.7inches, they are big enough to be noticed but do not completely cover the window pane so you can still see out. Easy to Use and Remove: you only need to clean the surface and paste the window stickers with water. These stickers can be removed easily without leaving any residue on the window, and can be used again. A Must Have for Halloween: these are really attractive Halloween window clings to make your Halloween party more funny. They stick very well to any smooth surface (windows, tiles, some kitchen cabinets, doors, car, cups, glasses, etc). Great for Halloween Party
