Much better than a regular stapler. Large stacks of A3 or A2 documents are absolutely impossible to staple together. If you try, the paper either crumples or you can't staple it in the center. For professional, straightforward, and easy stapling, you should use the Leitz 5560 long-arm stapler. Thanks to its perfectly thought-out design, this stapler is absolutely precise. It is so robust and reliable that it can staple up to 40 sheets of paper at once without any issues. Made of metal, it is more durable and lasts for many years, which is also confirmed by the ten-year warranty. Its mechanism is precise as well. You always know exactly where it staples. Additionally, there are no staple jams.
