These 12 oz. vintage reproduction enamel mugs are made from a thick enamel-coated steel. They are heavy (for enamel mugs-- still lighter than ceramic), smooth, wonderful to drink from, and crazy sturdy. Each mug is hand-printed and made in the USA.
- These mugs are not microwave safe. (Steel and microwaves don't mix).
- They are dishwasher safe and won't fade.
