Curved to fit comfortably in your hand, each Frank Green mug is one-of-a-kind. They are made of ceramic and stainless steel and each mug is triple-walled and vacuum insulated, keeping your coffee or tea hot or cold for much longer than your typical cup. Frank Green's one-handed push-button design is built to help retain the temperature of your drinks and to create a leak-proof seal, making it perfect to toss in your bag on-the-go.
In as little as 15 uses you’ll begin to offset the environmental impact it took to create your ceramic mug, and the best part, is that each cup is 100% recyclable at end of life.
For the best heat retention, keep your lid on and the button closed unless drinking.
They are BPA free, FDA/EU approved
How to wash: Hand wash with warm or cold water and a mild soap.
Do not put in microwave.
