Sango Gold Dust Black jumbo mugs are great for soup, cappuccino--or even those foods you want to transport from kitchen to wherever! The Gold Dust style recalls artisan pottery with its simple shapes and bold contrasting glaze effects. The pottery is fired in the kiln once for each of the colors. There are glaze, color, and surface variations, so no two pieces are exactly the same. Microwave and dishwasher safe and lead free glaze.
