The tumbler is filled with mixed shape stainless steel shot. It contains different shapes like pins, ellipses and ovals that help get into the crevices of your jewelry. I use my tumbler with copper, brass, sterling silver, and gold filled wires. I don't often use it for plated wires because it will wear off the finish. Hope that helps.
What is the wire? What is in the tumbler to do this ?
