Pretty Bad Can maybe punch a hole in one piece of paper. If you need it for anything other than maybe two pieces of paper at a time do not get it. I only wanted to punch a hole in a paper that was tapped and it took three tries before it went through.
This product works for a few pieces of paper only. I attempted to punch a hole in a leather belt. Further I don't remember whether there was a warning or not in the packaging. My mistake.
