    Good learning tool
  

*by B***R on Reviewed in the United States on January 20, 2020*

Good learning tool. Im trying to teach myself how to eye ball sizes of pipes and fittings. This is very helpful. I try to give my best guess and then i check it. This is great for at home and people in pipe businesses to learn or just check their work. The ones i purchased are accurate.
