Stronger for thicker

These clips are planned to assemble up to 60 sheets, they are bevelled on their ends to better penetrate the thick leaves and they adapt smoothly on staplers planned (I have a clip stapler Rapid Classic K1 Inox).
I would add that they are zinc color, in accordance with the color that can be seen in the small round window on the video box and they are very good.
In short, they do very well the work for which they were designed.
