The hole punch was sturdy and could be used with ease for the sheet capacity recommended. We actually purchased it to be used with construction paper and no problems with the extra thickness of the paper.
I had a one hole puncher for many years and finally had to go and replace it with a new one. The one at Staples has been much improved over the years since the paper that is punched out get to remain within the chamber on the punch. This is very efficient since I used to have to clean up all the paper that was punched out - they would be everywhere. I am very pleased with this purchase even though it was a small one. Once again Staples has provided me with a necessary tool to keep my office in great and clean shape!
