Our friend Masa made this classic white ceramic mug for us, featuring the Harney & Sons logo in grey. It's extremely sturdy and holds a generous 15 oz of tea. Masa always makes stylish and functional pieces; we know you will love it. Don't worry, we're not watching, so if you really want to use your Harney mug for a cup of coffee, that's ok on occasion! Dishwasher and microwave safe.
