To be completely honest, this mug did not live up to my expectation of quality. Admittedly, my expectations are often considered high, especially when it comes to quality. The description says "cold cast bronze" and that it has "painted highlights" so I was expecting the metallic sheen shown in the photos to be polished metal. Alas it appears to be entirely painted, and if you happen to scratch it, the metal underneath the paint is dark and dull. Regardless, I am still quite happy with it overall. It is heavy and sturdy, and as an added bonus, the lid from a long gone Yeti-mug that I mangled at work fits perfectly into the mouth of the stainless steel insert, so that was pretty nifty.
