Original packaging (clear reusable cylinder shown in photos) works great. I bought these, changed from a thicker silver clip to a light green clip that doesn't fire all 5, needs removing (pull nose, use knife to remove warped and partially burned ones, then grab caps). I had more of the old staples, not a single misfire or problem. Obviously the staples have changed for the worse, which is bad for a guy with a make up cap stapler.
