For the uninitiated, Egg Shell stickers are unlike traditional paper or vinyl stickers. Not only can they adhere to the most ridiculous and unaccommodating of surfaces, but they're nearly impossible to break and peel off. Do you have something important that you need to say and display? Something important enough that the person in charge of taking it down will have a real tough time and probably give up before they succeed? Then these are the stickers for you.
