 Heat Changing Love Mug Heat Changing Love Mug is decorated with dots of pink small hearts that are not too clear at first glance. Upon making your spouse’s favorite hot beverage, the heat from within will make the tiny hearts say the three words — “I Love You.” The ability to change its color stems from the thermochrome coating on the mug, where it will become transparent when hot liquid is poured in, to make the message visible. This is hand-wash only, so keep it away from dishwashers or microwaves. It costs US$14. |
