This is an excellent, over-sized mug with a bright demeanor given off by the white exterior and orange interior. I believe it was produced around 2010 and is a promotional for the Junior Diabetes Research Foundation "Walk To Cure Diabetes" drive. The cup is practically flawless, with no abrasions, cracks, or chips anywhere on the mug.. Dimensions: 4 1/2" Tall 3 3/4" Mouth Diameter 2 3/8" Base Diameter 4 7/8" Wide at Handle This cup will service those with a thirst (need?) for an extra few drinks between top-ups!
