Save birds from window collisions with these fantastic Mushroom Window Gems.  They break up reflections on the glass and warn birds away in time to avoid window strikes.   And they are just plain fun; we even included a little frog for you to place under one of the mushrooms.   The decals stick to the window purely with static cling, not adhesives, so they are movable, reusable and never fade. Comes in a package of 11 individual clings, with 10 mushrooms and 1 frog.  They range in size from  2" to 8" tall Handmade in Mount Shasta, California 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.
