Solid copper as described and worked great
I was having high heat and high resistance issues on 3/8 inch connections to a high current bus bar in a battery / inverter system. I put one washer above and below each cable connection and tightened them down. This resulted in a significant decrease in both voltage drop across the connections and heat generated at the posts as verified with a volt meter and a thermal camera.

Thicker than most washer
Using for oil drain plugs although most have a slight difference when put on the thread but you can always use a drill bit and some lub to widen the inner diameter.

Looks to be copper
One reviewer said these are just copper plated zinc or some other core metal. I broke one open and they seem to be all copper and not just copper plated.

Very cool for stamping
Love! Used these to stamp and make bracelets! The teens love them and adults. When the get get wet they discolor but are still cool!

Are they really copper?
Bought these to make stamped tags with. They seem much harder than copper. Don't take a stamp readily, and they break like white metal.Thinking they're not copper so much as copper colored white metal.

Copper washers
I think they are fab as a sealing washer on my motorcycle sump nut.original part is £3 a time,this product is much less 35p ish each and there is 50 so that will probably outlive the motorcycle and can be used on my other bikes.Took a fair time to arrive from west Coast USA but was worth the wait and it was quite entertaining watching the tracking data still surprisingly arrived early.
