3D3DNice copper cup.
This is a nicely hammered copper cup I got in Japan. It was sold as a health-related object, not surprising since copper is often claimed to have various beneficial effects. Which of course doesn't make much sense when you consider that it doesn't dissolve in water, and even if it did, this cup is lined with some other metal that would prevent you from getting any copper from it. I think it's supposed to be some kind of energy nonsense, people also wear copper bracelets that are said to have similarly non-existent positive effects despite staying entirely outside your body.
