Envelope X-Ray Spray
Ever wanted to take a peek at an envelopes contents without actually slicing it open? Then grab a can of Envelope X-Ray Spray, a simple point-and-spray solution that temporarily turns opaque paper translucent for a quick read before it evaporates off 30 seconds later, leaving no one the wiser. Of course, there’s the matter of it being sort of illegal to use it on someone else’s mail and all, but hey, it isn’t illegal if you don’t get caught, right? But… just don’t.
