These mugs measure 4" tall and 3" wide at the rim. They are glazed in a white shino which breaks in a rust red over the imprint. It also has speckles of the rust red. I love the way it highlights the imprint without being "in your face"! These mugs are perfect for gifts when given with a pound of fair trade coffee or wonderful herb tea. Great for college students, teachers, your best friend or you :) Kings Creek Pottery is food safe. These mugs can go in the microwave and dishwasher.
