Bundle up to 25 sheets with the blue Rapesco Flat Clinch Half Strip stapler. The Flat Clinch mechanism pushes the staples completely flat on the underside of the paper to prevent sharp, protruding points. This also makes it easier to stack bundled paper. The stapler has a rubber foot and an insertion depth of 49mm. This plastic device accepts size 24/6 and 26/6 staples.
