Going out to dinner lately has gotten to be nothing but a table full of people playing with their phones. Well if this sounds familiar, then it's time to get one of these cool new Phonekerchiefs. When an annoying phone comes out, just snatch it away and wrap it up in this phone handkerchief to effectively kill the signal and restore some manners to the table. This innovative, service-blocking handkerchief is made with silver fibers to block incoming calls and texts, but still sends a clear message. Quite possibly the greatest invention ever made!
