Fall is the best. Crisp days, leaves falling, warm drinks, and a ready-made excuse not to leave your house: dude, it's cold and rainy. Who wants to go out when you could stay in with a book and a cup of tea? Duh. Our vintage 12oz 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. Dishwasher safe. These are steel under enamel. So please don't use them in the microwave.
