Ceramic Mugs (white handles) are microwave/dishwasher safe. Ceramic Mugs (black handles) are too but we recommended to only be hand-washed. COLOR: Please note that color varies from computer screen to computer screen. Colors are represented as accurately as possible. Because Mug artwork is ink-jet printed on to ceramic mugs this process makes them both microwave and dishwasher safe. May be cleaned in dishwasher - however- we recommend washing by hand with warm water and dish soap to extend the life of the art.
