Quiet, featuring a large 30L bin capacity (275 A4 sheets) and easy-to-use, touch control buttons. Shredded to a high security level using P4 Cross Cut pieces measuring 4x40mm. * Shredder machines are not covered by warranty; they can easily shred multiple documents, even ones with staples and paperclips on the corners.
