Thank you for viewing. This is a hand-crank shredder for home use that can finely shred A4 paper. It also has a function to damage CDs by inserting them into the front part of the shredder, making them unreadable. Home Shredder AS480CR - Brand: AURORA - Model: AS480CR - Function: Home shredder I am selling this because I purchased an electric shredder as I had more items to shred. There is some yellowing on the top of the unit, and there may be a few paper scraps left over after shredding during shipping. Also, there is a slight squeaking sound when turning the hand crank (from the beginning?). If you have any questions, please feel free to ask.
