Professional-grade copper sheet metal in a 12" × 12" square format, available in six gauges ranging from 16 to 26 gauge. Each sheet is sold individually and arrives straight from the mill — unpolished and unfinished — making it ideal for jewelers, metalsmiths, and fabricators who prefer to work from raw stock. One face ships with a removable plastic protective coating to minimize surface scratches during transit. Natural surface discolorations from the milling process may be present and can be easily polished away.
