Mugs are more than just a cup to hold a liquid. They are statements of one's personality and great conversation pieces. The Stonehenge mugs certainly make their own statement and allow owners to do the same. Made of porcelain, each white, 11-oz. mug has a distinct silk-screened Stonehenge image. One brings to life the Hidden Halos of Stonehenge, as golden rings appear when hot liquid is poured in the mug.
