Review on 🔧 Stainless Precision Repairing Toolset: Afrowlle Assortment by Lamar Marshall

With the accuracy with which my microgram balance and the best 0.01mm precision calipers could measure the largest bearings, the density of this great metal is 7.747 g/cm3 at room temperature, but if I froze them in the freezer for an hour and their diameter decreased by 0.01mm increasing their density to 7.781g/cc, I wonder what to do with this knowledge.
