Pen concealing hidden transmitter

For easy and fast concealment, the pen bug is ideal. It is a fully functional pen concealing a hidden transmitter that can pick up the slightest whisper up to 40 feet away and transmit to our air band receiver up to a distance of 300 metres away with amazing clarity. The pen is powered by 2 easily obtainable watch batteries and is completely inconspicuous. Even under close examination, nothing unusual can be seen and if used, it will even write as well.
