This DC Comics Harley Quinn Heat Changing Mug is as changeable as the fantabulous anti-hero herself! When cold, the mug has a black base colour, dotted with small heart and diamond cut-out designs which provide a sneak peak at the design beneath.
When hot liquid is poured into the mug, it transforms to reveal vibrant wraparound artwork of Harley Quinn which fades as the drink cools.
