This set of two Doctor Who cold changing drinking glasses is perfect for a nice cold drink after travelling through the galaxy. Cold, the glasses show the Tardis and a Dalek in white on the front and the words "Time Lord" and "Exterminate! Disintegrate!" respectively on the back. When cold liquid is poured in, the designs change to different shades of blue, bringing these Doctor Who icons to life. Housed in a gift box, this is the perfect addition to any Doctor Who display.
