That's pretty cool. What my wife had made is a metal coffee cup on the inside with a seal over the white paint that can be washed just like a regular cup. She could have had the cup painted any color. She knew I'd want the color of my car. If I had a red car, I would have got red and so forth... Keeps my coffee nice and hot with the hour drive to work. Gotta love it!!!If you get to a racing event where Hyundai has a booth they hand out squeeze type thermos bottles with a big N on the side.
