Folks just love our EDCO copper foil. Made of "dead soft" copper, it is just as the name implies, soft! This softness makes it easy to work with. It offers little resistance to being shaped and it bends easily. It conforms easily to the glass, and adheres very well. 3/16" x 36 yds x .001 (Narrower than the standard 7/32".) Please limit your purchases to SIX (6) rolls of foil.
