Query: Look nice, but corrode immediately

I don't really care if I had a copper cup that tarnished, but when the selling point of a product is that it has a thin lacquer to prevent this and it doesn't do it...then i say BS. These have been used once, never in a dishwasher, and I have black spots forming all over them. Weight is just like any other cheap copper cup out there. You are not getting any better quality here. They are still pretty chintzy. Nice design, but not worth the price.
