The mug looks really nice from the outside. Its very shiny and looks good quality. I ordered two of those. One came in very nice and no flaw. However the second one (as shown in pictures) had an ugly and unhealthy layer of GREEN something inside of it. Looked like oxidized copper or what. However the photo i took is after 15 minutes of scrubbing and trying to clean that off. I dont feel very safe drinking from it to be honest. And not sure if it will come off alltogether. The other one is ok though...
love it.
