◎ Copper round bar φ26mm × 255mm Approximately 1.1kg Since I do not have a way to clearly determine the material and purity, it is unknown. Please make your judgment carefully. This item was found in a warehouse, covered in black tarnish and verdigris (mold?). It has been thoroughly scrubbed with stainless steel wool. It will tarnish again within a few months. ■ Condition: I believe it is copper because it had verdigris like a 10-yen coin. A magnet does not react to it. I have confirmed electrical conductivity with a small light bulb. The surface is rough, and the cut surface has irregularities. ※※※ This item has been left in my parents' warehouse for over 30 years. I will sell it to someone who appreciates copper. /※ Gunmetal, brass, bronze, zinc ※/
