Great deal to last you a long time
Bought for my dirtbike so I would always have some available and not have to go to the dealer and get ripped off on a single one.

Good quality and good value
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.

It is faithful to its function.
I used it once, and there was no problem. I just wanted a slightly thicker product when I bought it, but I couldn’t find one on Amazon. I just hope there won’t be any problems in the future.

Pure copper and will tarnish as expected
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.
