Our Huge Hummingbird with Watercolour Wildflower Meadow Windows Clings are double-sided printed so that you can see the image from both sides of the window. They also great as party decorations, can be applied to windows, doors, floor, fridge, glasses, bathroom, home appliance, air-condition, office, dorm, or retail store. Our clings are without glue, and you can reuse them how many times you want! To install, make sure the surface is clean and smooth, spray a little water on the window to paste it better. To help to prevent the collisons, apply the elements not far from 10cm or 4 inch of each other. Easy and convenient to remove without damaging the glass. Each packaging contains 12 sheets of 30 x 20 cm or 11.8 x 7.8 inch, with 98 clings in total. Finishing size: 105 x 91 cm or 41.5 x 35.8 inches.
