Review on Vernier Caliper Precision Essential Jewelers: Achieve Unparalleled Precision in Jewelry Making by Chris Cruz

They're good (for what they are, plastic calipers) and the seal was clearly marked, but as they were 33% more expensive than the big 6" calipers sold at Revain I found them Overall quality of the calipers too light for me so when lifting I always have to be careful that the part that slides out of the body doesn't catch on anything and break off, and added a bit of extra work to align the piece with the thumb to measure. All in all, these aren't bad calipers, but as I felt that for that 33% premium compared to the 6" models (especially since they're 25% smaller), there would have been a little less "play" in the fit. Share to make them easier to work with.
