Ingenious. Practical. Ridiculously cute. Just put your tea in the strainer, plop the lid on the cup, and steep. Then easy clean-up: remove the lid/strainer, tip it upside down and looky here: the lid becomes a saucer for the strainer. Since most fine teas are actually better on a second infusion, you can save the tea and use it again for your second cup. Cheers! The mug is microwave safe (not the strainer!), and both can be cleaned in the dishwasher.
