I booklets very much, even with more than three leaves, I have re-elected a stapler Leitz. My old Leitz Stapler I had about 5 years, and he went through a lot. Also new this is again made of metal. Metal stapler are simply more durable. For 30 years, accompany Me products by Leitz with exclusively high quality. When I've tried something else cheaper hats, not last long. Nevertheless, this stapler is not overpriced. Good value for money. I can only recommend.
