This mug is one of the few that is a retail purchase (that is, not promotional give-away.) The mug has a full wrap around design of a pink and blue checkerboard and on the left side is "I love exercise" above a drawing of a set of exercise weights.
When hot liquid is added to the mug, the set of weights clears....well, it's supposed to clear. The pic above shows the mug full of hot water, and the weights are only slightly less opaque. If you look close, you can see the other design, a set of glasses, through which you can see a man's form working out with weights. Below the glasses it says "I can watch it all day!"
Though the mug is in great condition, this is one of the very few mugs that does not change well. Most others usually have UV or Microwave damage and show a light brown semi opaque covering. This mug shows the colors correctly, but the color change just doesn't happen properly.
A retail type mug, it's still a great addition to my collection.
