These Bodum thermal mugs combine form with function. They're very well insulated and classy. But they're also light and fragile borosilicate glass, so hand wash or use caution when placing in the dishwasher. This 15oz size is about as large as you'd want a hot/cold beverage cup and Bodum also makes several smaller sizes and shapes.
These Bodum mugs are handmade, so will each have an individual look. Yes, they're a good value, but they're not bargains. Let's face it: they're as pricey as art glass, because they ARE art glass. My Bodum mugs go through the dishwasher, but are loaded into the top rack very carefully.
