I use the copper washers for jewellery making and wanted pure copper that I can treat with liver of sulphur to age and tarnish. I can confirm that these rings will tarnish and the effects I've achieved are as exp.

I needed just a couple, but this was a good value and since I bought the set, I have used more than just a couple....They serve more than one application and seal very well....If you're doing anything mechanical, you'll run into a need for these sooner than later and pay twice as much for fewer at the stores...Bottom line, g good buy.
