A mix of copper wires from a camper and leftovers from a house. I stripped them all myself, the house wires are thick while the camper wire is similar to speaker wire. Also a bunch of copper pipe I cut down. The rest of the stuff is a mix of copper and brass, just knick knacks I’ve found metal detecting and other sorts of treasure hunting. I wanted to melt this down but I will never get around to it. Sold as pictured.
