Just when you thought handkerchiefs were so yesterday, out pops the Phonekerchief. This hi-tech handkerchief is not just a conversational piece. Its "smart material" actually blocks phone signals if you wrap up your phone in it.
Just so you don't get the evil eye from your colleagues at that next business meeting, the hi-tech handkerchief has the words "My Phone is Off For You" right at the corner. Tuck your Phonekerchief-covered phone into your breast jacket pocket just so, and you are all set to let everyone know you're considerate!
