I have been looking for a solid copper thing to make a bracelet with for a few years now. I found this on Amazon for around $10 bucks. I was skeptical, but when I got it, very fast I must add, I was very pleased. Its nothing fancy, but also not ugly. I could not have wanted it any other way, exactly what I have been looking for. As far as for pain, I have no idea? I get pain medication from the VA that makes it kind of goofy to figure out what really hurts anymore, or where. I got it to go with my brass ring I wear on my neck. When I spearfish, the copper and brass make an electrical signal in the water that draws fish. Turns me into a human fishing lure. I hear it will draw in sharks too? If I survive, I will let you know how that went. Great product, exactly how its described on Amazon. Could not be more pleased.
