Koper Metallic Folietape

The peel-off paper backing makes this so much easier to work with than I expected, and it presses down smooth without wrinkling. I've been using it to line the edges of a jewelry box and the copper takes on a nice patina within days. A 25-meter roll goes way further than I thought it would.

I wasn't expecting real copper, but this stuff patinas and everything. The peel-off backing makes it way easier to use than the foil sheets I tried before. One 25-meter roll has lasted me months of small craft projects.

The copper is genuinely soft and malleable, so it wraps around curved edges without cracking or peeling up. I used it to shield the inside of a guitar cavity and the paper backing came off clean with no residue. Twenty-five meters goes a lot further than I expected.
