This infusion mug has three pieces - the cup, the lid and the strainer. The cup is 4" tall and 2.75" in diameter, The strainer is 3" in diameter at the top and 2.5" tall. The lid is 3" in diameter and 1" tall. Total height is 5.5". The designs on the cup and lid are Oriental women and branches. There is a trademark on the bottom but I do not recognize it. All pieces are in good condition.
