Highly polished stainless steel shot mixture known as the “Jewelers’ Mix” is a combination of three shapes: diagonal round and pin. Each does a different job in burnishing metals to a mirror bright finish in the minimum amount of time. For almost all applications it is the only shot combination you’ll ever need. Stainless steel requires only occasional cleaning and gives great uniformity. Because it is stainless steel it is rust and corrosion resistant and able to stand up to strong compounds. 2 lbs.
