This is a Nakabayashi household handheld shredder. It uses a micro-cut (2x10mm) to shred documents. It can shred 2 sheets of A4 paper at a time, as well as plastic cards and CDs. (Cards are cut into 5 pieces, CDs into 3 pieces) I have used it a few times, but there are no noticeable scratches or stains. This is a used item, so please refrain from purchasing if you are concerned about minor details. It will be shipped via Mercari Takkyubin.
