Inspired by the timeless words of Nelson Mandela, the Impossible is Done Edition is engraved with a quote that has moved mountains. It's a mug for barrier-breakers, boundary-pushers, and anyone in the middle of something that feels too big...until it isn't.
With Ember's patented temperature control technology, your drink stays warm through every late night, early morning, and breakthrough moment along the way. A reminder that impossible is just a word.
All custom Ember Mugs are made to order and are final sale.
The 14oz Mug only heats. For cold, see the Cold Tumbler — same control, opposite direction.
Yes — the Ember app is on both the App Store and Google Play.
Hand wash only. The electronics are sealed (IPX7), but dishwasher heat can damage internal components over time.
