This clever device hides a small recording camera and microphone into the case of a pen (that still writes). Can be used for covertly recording images and speech. 2GB storage capacity. USB 2 connector for downloading. Integrated battery allows for up to two hours recording time. Only used once. My nephew is getting rid of a lot of stuff due to a rewire. He has two of these to sell, separately, at £5 each but one of the boxes has a slight tear in the bottom as shown in picture.
