Holly carries Artemis and Butler in her cam foil

Cam Foil is one of Foaly's many inventions. The surface of the foil is covered in Fairy-manufactured micro-circuitry which can analyze the wearers surroundings and display what is behind the wearer on the front and so on, hence making the user appear nearly invisible.


Unfortunately, it has weaknesses, including:

  • One shower of rain can short out the whole thing.
  • The circuitry can very easily be crushed, as No. 1 proved when trying to escape from Minerva Paradizo.
  • The foil is useless against cameras.
  • The user appears as a slight heat haze, so is still noticeable.
