With the Esselte Leitz Super Hole Punch, you can punch through paper stacks up to 25 mm thick or up to 250 sheets in one go. This allows you to quickly punch thick dossiers for filing or pre-punch an entire stack of printer paper. The Powersave technology and the particularly long lever ensure that this is done with very little effort. The stable, easy-to-read metal alignment guide ensures that your paper is cleanly aligned and centered up to A3 size. A cover for the punch heads provides safety.
