A bigger mug for bigger mornings

If one cup of coffee is never quite enough, these 18 oz mugs hold more than most standard mugs. They are made of sturdy, lead-free and cadmium-free ceramic with a glossy glaze that looks great on the kitchen counter or your office desk. The question-mark-shaped handle keeps the mug from twisting in your hand, so you can sip comfortably. Use them for hot coffee, tea, cocoa or cold drinks, then pop them in the microwave or dishwasher.

Why you'll love it

  • Big capacity: 18 oz holds more coffee or tea than a standard mug.
  • Safe ceramic: Lead-free and cadmium-free for everyday peace of mind.
  • Steady grip: A question-mark handle that won't rotate when you hold it.
  • Easy care: Dishwasher and microwave safe.
  • Classic look: A simple shape with a glossy glaze in rich colors.

Perfect for: Morning coffee, afternoon tea, the office desk, cozy winter cocoa
