Ember Temperature Control Mug

NIB never used. 14 Oz / 414 mL. Color is slate grey. I opened the box to examine the mug, but did not use. Designed for home or office, the new Ember Mug² does more than simply keep your coffee hot. Our smart mug allows you to set an exact drinking temperature, so your coffee is never too hot, or too cold. Ember then maintains your chosen temperature for up to 1.5 hours with the Ember Mug² 10 oz and up to 80 minutes with the Ember Mug² 14 oz - so your hot beverage stays perfect. Ember Mug² is safe to hand wash and submersible up to 1 meter in water.
