Nakabayashi Personal Shredder NSE-307 Automatic CD A4 This is an electric shredder that I no longer use. It can shred up to 3 sheets of A4 paper at once, and is also usable for CDs, DVDs, and cards. I have done some basic cleaning, but there are scratches and dirt. There are also paper fragments that I couldn't remove attached to the blades. There were no problems with the operation, but please be aware of this beforehand. I think it will be useful for discarding documents, letters, etc. There is no box or instruction manual.
