The 2nd Pair of Paper Shredding Shafts re shreds the document again to Levels P6 which to the naked eye is complete dust particles, in actual fact the finished particle size for Security Level P6 is 0.8mm x 12mm.
It is common for this level of security to be expected and in some cases made compulsory in order to comply with Government, Military or USA standards.
