The 16 oz mug is a pleasing nearly spherical form. It picks up on the puffy donut shape and the Q in the SuzyQ logo. It was designed to be the same height and width as the 12oz mug. The volume difference is gained by it`s curvature. In later iterations of this mug the designed was modified to favour a larger handle and a logo sprig was added to the side of each mug in random positions.
