This unique design of colour changing mug is perfect for making a surprise wedding proposal! It is black when cold, but when hot water is added it transforms into a beautiful blue and cream striped design, complete with red love hearts and the message "Will you marry me?".
The mug has a straight-sided design with an 11 ounce (313ml) capacity, and is both dishwasher and microwave safe. After printing, it is finished with a protective polished ceramic glaze which makes it extremely durable, scratch and chip resistant.
