20號（0.032英吋）銅片 12" x 12"

The anti-tarnish film was still on when it arrived, which saved me from having to polish it before cutting. Cut cleanly with regular shears, and the 12x12 size gave me plenty of material for several small projects.

I needed a square for a jewelry project and was relieved to find this already cut cleanly at 12x12 with sharp edges that saved me the hassle of trimming. The copper has a nice weight to it and the film peeled off easily without leaving any residue. It's already making my metalwork look much more pro

The anti-tarnish film is a game changer—no scrubbing off oxidation before I start. I used it for a jewelry backing piece and the 20-gauge thickness held its shape perfectly under the hammer.
