Inexpensive tools made in China can be anywhere. There are great things made in China and poor quality things (like everywhere else). Whatever factory made these squares (I had 4" and 7" sets) did a great job. It was easy for me to try them knowing that I could buy them and if they were defective, send them back for free. You are fantastic. I'm happy to pay for the quality. But in this case I got much better quality than I expected for $77.
