This is a Nakabayashi home shredder. It can shred up to 5 sheets of A4 paper at once, folded in half. CDs can also be shredded. Continuous usage time is 3 minutes. I purchased it over 10 years ago and used it a few times. Size: 18 x 22.5 x 28 cm Weight: Surprisingly heavy at 5.8 kg. I'm selling it because I don't use it often. Thank you for looking.
