Strips but much too wide. Sensitive documents can be easily reassembled. What is a shredder for? Absolutely useless product. I'm returning the item by return of post. Too bad I have already disposed of the original packaging... Why Galaxus sells such a bad product at all is absolutely incomprehensible to me. My guess is that none of the Galaxus people have ever used it. It's a shame, otherwise my experience with Galaxus has been good, but the quality is declining with the breadth of the range.
