Bright up your windows with colour and beauty, prevent real birds to collide on your windows. Our Big Hummingbird 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 in of each other. Easy and convenient to remove without damaging the glass. Each packaging contains 3 sheets of 30 x 20 cm or 11.8 x 7.8 in with 15 big birds and 14 leaf
