Stainless Steel Magnetic Balls For Magnetic Tumblers-1.2mm 50 Gram Pack

These 1.2mm size stainless steel round magnetic balls will do absolutely nothing when used by themselves, but when added to the 0.3mm or 0.5mm pins, they will act like tiny ball bearings to improve the action of the pins. Just like the steel pins, for best results they will require a break in period.  Sold in a 50 gram package.
