Save birds from window collisions with our adorable Mini Forest Friends Window Gems. These little guys are happy to hang out on your window just being cute. Great for kids to move around as they please on the inside of windows. They can also go on the outside of windows where they can break up reflections on the glass and warn birds away in time to avoid window strikes. Comes in a pack of 8 woodland critters ranging in size from about 5" for the baby deer to 2" for the littlest mouse. The decals stick to the window purely with static cling, not adhesives, so they are movable, reusable and never fade. Window Gems are made with a colorless translucent prismatic vinyl which captures sunlight and turns it into sparkly rainbows. They are stunning, constantly changing, and perhaps a teeny bit magical. Any bright light source makes the gems glow with rainbows, even moonlight.
