This is a COPPER100 pure copper mug from Shinkou Metal. It is a new, unused item. I took the photos with the plastic bag still on to prevent it from getting dirty. I kept it stored away because I felt it was a waste to use, so I am selling it now. Please understand that as it has been stored for a long time, there may be some minor scratches or scuffs, and it is considered a used item. I would be happy if someone would use and enjoy it.
