Friday the 13th Heat Change Mug
Each time you fill this 300ml (10.1fl oz) Friday the 13th Heat Change Mug with your favourite hot beverage, watch as the plain black areas on the outside are transformed into a full-colour wrap-around blood-soaked design. Featuring the trademark hockey goalie mask worn by Jason Voorhees in Friday the 13th Part III on one side, and a Camp Crystal Lake decal on the reverse. As your hot drink cools down the mug will revert to its original look ready for you to enjoy the amazing transforming action the next time you add a steaming hot brew.
