I do not why there this still so small.
Most could plate with copper sulfate aka for garden store as root killer and a old USB charger.?
Any can make name plates with copier?

Then chrome just use nickel over copper.
Nickel is very first think I used when was 10.

I have even try the way Roman's did 2000 years ago copper plating and worked.
