Our 11oz triple AAA grade ceramic color change mugs have a super photo quality heat sensitive coating that produces stunning image reproduction. When hot liquid is poured into the mug the coating becomes transparent revealing the gorgeous Ready to Wear by AhVero artwork underneath in all its glory. Then, as the mug cools, the heat sensitive coating restores to its original black color, a gentle reminder that it may be time for a second cup of your favorite hot beverage.
