Whimsical mugs in one of a kind dot pattern. No two mugs are identical. Purchase a one of a kind mug or get more than one in a slightly mismatched set. These cups have matt underglaze dots and have been intentional left unglazed on the exterior. They have been glazed on the interior so they are ready for coffee, tea or whatever hot beverage you enjoy. They can be put in the dishwasher and microwave. They hold a good 10 ounces of liquid and measure 3.75 inches in height and are 3.75 inches in diameter.
