Thermal coffee cup

My husband used to use a little electric coffee warmer. He would set his coffeecup onto this device and it , of course, kept his coffee warm. This was until he stopped using it as he almost set the homeoffice on fire more than once by getting paper too close. So, I am looking for a nice looking thermal coffeecup. Not the big clunky mugs with gas station logos on but something that looks very nice. Can't seem to find. Has anyone ever seen such an item? Thanks Liz
