Send the right signal by giving dinner partners your undivided attention with this innovative, service-blocking hanky made with silver fibers that effectively block incoming calls and texts. "My phone is off for you," says it all, so you can, too. 

How It Works: The Phonekerchief fabric is conductive (conducts electricity) because it is partially made up of silver fibers. When the fabric creates an unbroken enclosure (when it is wrapped tightly around a phone without any gaps), it creates a phenomenon that is known in science as a "Faraday Cage". This means that any external static electrical field, such as a phone signal, will cause the electrical charges within the conducting fabric to redistribute themselves so as to cancel the field's effects on what is inside.

Please note: In order for the Phonekerchief to work effectively, the fabric must be wrapped tightly around the phone and create an unbroken enclosure.

    i'm assuming this is meant for an occasion where you honor and give focus to someone else. this is clever but in reality it is bringing the attention to the wearer. :/
