These are specially made "MINI SCRATCH ERASERS" but in a THIN variant for very intricate areas in your small jewelry items. They burnish metal & give it a pre-polished look. The shank is included in this kit. Shank/mandrel diameter is 3/32″ (2.38 mm). This is one of Anie’s favorite abrasives. Available in COARSE, MEDIUM, FINE and VERY FINE as a full combo set of 4 grades (1 pc per grade = 4 pcs total).Jewelry applications: It’s excellent for cleaning castings, “wiping off” or “blending in” scratches and scuff marks on precious metals. It is also great for removing porosity & parting lines in jewelry castings. It does not remove your precious material. Instead, it burnishes and spreads it along the surface. Simply follow up with the THIN FELT wheel for a finished, polished look.
