They're unbranded, made in China, and brand new – never used.
PP is a lightweight, corrosion-resistant, and non-conductive plastic, so these balls are great for applications where you can't use steel – think chemical pumps, food handling, or low-load bearings where rust is a problem.
They're precision-molded to be fairly round and consistent, so they roll smooth in a race or work as check balls in valves.
