For the readers who lose track of time—and temperature.
Welcome to your Bookish Era—where the to-do list can wait, and the tea stays warm as long as the chapter is good. Featuring an engraved illustration of a steaming mug atop a stack of books, this edition is a love letter to slow mornings, late-night reads, and literary daydreams.
With Ember’s precision temperature control, your drink stays perfectly warm from page one to “just one more chapter.” The perfect gift for book lovers, writers, students, and quiet corner dwellers.
All custom Ember Mugs are made to order and are final sale. Allow up to 5 business days in addition to normal shipping and handling.
