Years and years of personal computer use has conditioned humanity to feel a sense a dread, of worry, and stress, whenever they see a warning message. So if you need to leave someone a note that they absolutely can’t ignore, what better way than with a pack of fake Windows error message sticky notes?
Five bucks gets you a stack of both ‘Error’ and ‘Warning’ messages so it’s up to you to decide how dire that phone call your co-worker needs to return really is. They might even be worth it for that adorable ‘blue screen of death’ packaging alone.
