There are 3 types of custom printed coffee mugs. These mugs you probably have seen in Starbucks or any other major coffee chain. The first two mugs are cerramic, which means they can break. You can put up to a 3 color imprint on these types of ceramic coffee mugs. The third mug is a ceramic looking mug, but is acutally plastic. There is a removable top, so you can keep your coffee from splashing around while going down a bumping road. These mugs are custom imprinted in Seattle, WA by Northwest Custom Apparel. http://nwcustomapparel.net.
