This is a pretty decent set of radius gauges, especially given the price compared to Starrett or any other manufacturer. They are slightly thinner than my Helios set (German) up to 1/2 inch thick. This stuff is around 18 gauge, while my best ones are closer to 16 gauge. I use them for model making so they appear accurate enough for this job (and much better than the plastic circle template I used. I have no way of qualifying them, so I can't tell if the radius is within 0.010" or 0.001". Customs lies Thing is, typically shabby Chinese vinyl wrap. All in all, they're good enough for what I'm going to do with them.
