Thermal Cup is a design by the fantastic Copenhagen-based design studio Tools Design for Eva Solo. I really loved this cup since the first moment I saw it because each design solution is perfect for a good reason.
How could you minimize the design of a cup? Take off the handle, create a double walled porcelain for a best insulation, and give it a soft, curved shape for a good ergonomics in your hand.
It even has a silicone rubber base to protect surfaces and to avoid on your serving tray.
