This is such a good find! This preowned diffuser mug is adorable and in great condition. It's ceramic featuring three parts, the mug, diffuser basket and steam catch. The mug is a large size and the diffuser basket designed accordingly. Enjoy your coffee or bag tea, or indulge in loose leaf tea and fruit infusions. I LOVE a fresh berry infusion into my English Breakfast tea! 
 
Some light signs of use should be expected.
