With Kokuyo's Harinacs stapler, you never have to refill with staples - there's simply no need! Is it black magic? Well, one would certainly think so at first glance. Harinacs Press staples paper together by pressing a kind of link pattern, which also means that there are no holes. If you want to separate your papers again, simply press hard on the pattern with the end of a pen.
Also available in a cut variant.
Manages to stalple about 5 sheets together.
