Cool cup. Liking it a lot

I bought this UNLINED cup for the benefits of the anti-microbial properties of copper...same reason people take silver colloid for health benefits. Copper is purported to be used in scalp shampoos as it reduces flaking and itching caused by microbes, especially fungi. This cup is beautiful and is for daily use. So what If it tarnishes. If it were lined I would not buy it. Attached is an excerpt from Wikipedia: "Copper and its alloys (brasses, bronzes, cupronickel, copper-nickel-zinc, and others) are natural antimicrobial materials. Ancient civilizations exploited the antimicrobial properties of copper long before the concept of microbes became understood in the nineteenth century.[1][2][3][unreliable medical source?] In addition to several copper medicinal preparations, it was also observed centuries ago that water contained in copper vessels or transported in copper conveyance systems was of better quality (i.e., no or little visible slime or biofouling formation) than water contained or transported in other materials."

Great mug, love it.

Use them every morning
