Polishes silver to a mirror shine.

As the item description says, these things are tiny, 3/4 inch. The longer description recommends ganging three of these at a time. I assume that’s so they will wear out faster. If you’re polishing hammered wire, two at a time works, and one might. I had hammered sterling silver earrings that had tarnished badly, and then been cleaned with BarKeepers Friend - no shine left (though it did remove most of the tarnish, at a cost of a lot of elbow grease). Found these discs on Amazon, mounted two on the enclosed mandrel, and attached it to my dremel. With the earring on a steel bench block, it took only a couple of minutes to polish both sides to a high polish. Anyone who makes wire jewelry, and has arthritic hands, should try this. IMO, it’s worth the cost of the dremel. Have already ordered the larger pack.Update: Their ability to polish seems to be limited to a couple of uses. Still like them; might try the Ernst Vetter (EVE) discs when I’ve used these up.
