Make yourself a coffeehouse-quality espresso at home, and pour it into an insulated cup. If you prefer tea, heat water in an electric kettle instead, and serve in a vacuum mug.
Double-walled glasses keep your drinks hot and they keep iced drinks cold as well.
When you're done with your drink, place the cup in the dishwasher for effortless cleanup.
Why go double walled?
The real question here is -- "Why not?"
Not only do these cups make any drink look more elegant when served, but the design also ensures a comfortable grip. Plus, double-walled cups also serve the function of maintaining the ideal temperature of your drink until the last sip.
