No matter what kind of day you've had, good or bad, exciting, or boring, quick paced, or slow, a cup of tea can always be trusted to wind down your day in the most calm and soothing manner. Therefore, we have created a mug in our Caleo collection specifically for tea. Following our Caleo's design, the tea mug in this series has a double wall application to maintain your dink's hot temperature while protecting your hands from the heat. The set of 10oz mugs are made of pristine hand-blown glass that can withstand a temperature of up 350 degrees Fahrenheit; this heat can be from the microwave, the liquid itself, a dishwasher or even an oven!
