This item is new/open box, has never been used but has been opened. Ember Mug² Metallic Collection is a brilliant new take on Ember’s classic smart mug, and is guaranteed to make every morning shine. Ember allows you to set your preferred drinking temperature, so you can enjoy your hot drink—just the way you like it— from the first sip to the last drop. Ember Mug² maintains your chosen drinking temperature for up to 1.5 hours with the built-in battery, or all day with the included charging coaster. Ember Mug² is safe to hand wash and submersible up to 1 meter in water.
