This is a new travel mug from Ganz. They are from a set of text mugs. This one says JK (just kidding for those of you text challenged). It is a multi-colored, insulated mug.
The top has a secure closure that slides open or closed for sipping and to prevent spills. Top pulls off and holds on with rubber rings. Very cool. As I said this is one of a set. For others click on view store. Thanks for looking.
